Ask most first-time watch brand founders what surprised them most about working with a Chinese OEM factory, and the answer is almost never the quality. It’s the time.
They expected eight weeks. It took five months. They planned a spring launch. The goods arrived in August. They approved a sample in October and assumed they’d have product for the holiday season. They didn’t.
This isn’t a story about unreliable factories. In most cases, the factory performed exactly as a watch factory should. The problem was that the brand came in with a timeline built on assumptions — assumptions that nobody had bothered to correct, because nobody had taken the time to explain how the process actually works from beginning to end.
That’s what this guide is for.
Working with a Chinese OEM watch manufacturer involves a sequence of distinct stages, each with its own requirements, its own decision points, and its own realistic time frame. Some of those stages move quickly. Others require patience that first-time buyers consistently underestimate. A few of them involve decisions that, if rushed, create problems that are expensive and time-consuming to unwind later.
The total journey — from your first inquiry email to the moment a pallet of finished watches clears customs and lands in your warehouse — typically runs somewhere between four and six months for a standard OEM project. For more complex designs involving unusual materials, custom movements, or multiple SKUs, it can run longer. For simpler projects with fast decision-making on both sides, it can occasionally come in under that range. But four to six months is the realistic planning number, and any business plan that assumes significantly less than that is carrying timeline risk that deserves to be named.
Understanding why it takes that long — and what is actually happening at each stage — does two things for you. First, it allows you to plan realistically, which means your launch dates, your inventory commitments, and your cash flow projections are based on how the process actually works rather than how you’d like it to work. Second, it shows you exactly where your own decisions and response times affect the schedule — because in a surprising number of cases, the variable that determines whether a project runs on time or runs late isn’t the factory. It’s the client.
This guide walks you through every stage of the process, from the first quote request to the final delivery. It covers what happens at each step, what you need to do and decide, what commonly goes wrong, and how to set yourself up to move through the whole thing as smoothly as possible.
If you’re placing your first OEM watch order, this is the orientation you should have received on day one. If you’ve done this before and hit unexpected delays, you’ll likely recognize some of what’s in here — and hopefully find a few things that make the next project go better.
The Big Picture — How Long Does This Actually Take?
Before we go stage by stage, it helps to have the full picture in front of you. Here’s how a standard OEM watch project breaks down across its major phases, with realistic time ranges for each.
Stage 1 — Initial Inquiry and Quotation: 1 to 2 weeks
You make contact with the factory, share your requirements, and receive a detailed quote. The speed of this stage depends almost entirely on how clearly you’ve defined what you need.
Stage 2 — Design Confirmation and Sampling: 6 to 10 weeks
This is the longest and most involved stage of the entire process. Designs are finalised, tooling is developed where needed, components are sourced, and the first physical sample is produced. Multiple rounds of revision are common.
Stage 3 — Sample Review and Approval: 2 to 4 weeks
You receive the sample, evaluate it, request any revisions, and formally approve it as the production benchmark. How long this takes is largely determined by how quickly you review and how clearly you communicate feedback.
Stage 4 — Mass Production: 4 to 6 weeks
Once the sample is approved and the production deposit is received, the factory moves into full production. Lead time varies based on order quantity, component availability, and the factory’s current production schedule.
Stage 5 — Quality Control, Packaging, and Shipment: 2 to 3 weeks
Finished goods go through final inspection, branded packaging is applied, and the order is prepared for shipment. Transit time to your destination adds further time on top of this — typically one to two weeks by air freight, or four to six weeks by sea.
Add it up and the realistic total, from first contact to goods in hand, sits at roughly 18 to 26 weeks — call it four to six months — under normal conditions. That number assumes reasonably smooth communication, no major design revisions after sampling, and no significant supply chain disruptions.
It also assumes you’re not running into any of the timeline variables that can quietly add weeks to a project without anyone flagging them as a problem. We’ll cover those in detail later. For now, the important thing is simply to have this overall frame in place before we go deeper into each stage.
What affects the total timeline most
Three variables account for the majority of timeline variation between projects. Understanding them helps you identify where your specific project sits relative to the average.
Design complexity. A watch with a standard round case, an off-the-shelf movement, a printed dial, and a leather strap moves through the sampling phase considerably faster than one with a custom case shape requiring new tooling, a modified movement, a multi-layer dial with applied indices, and a custom-fabricated clasp. Every element that requires bespoke development adds time — sometimes a little, sometimes a lot, depending on the complexity of the component and whether the factory has produced anything similar before.
Decision-making speed. This one is underappreciated. The factory’s timeline is punctuated by moments where the project stops and waits for your input — design approvals, sample feedback, quotation sign-off, payment processing, artwork confirmation for packaging. Each of these waiting periods is largely within your control. A client who reviews and responds within 24 to 48 hours moves through the process noticeably faster than one who takes a week or two at each decision point. Over the course of a full project, the cumulative difference can easily be a month or more.
Seasonal timing. The Chinese manufacturing calendar has two periods that significantly affect production schedules: Chinese New Year, which typically falls in late January or February and effectively pauses factory operations for two to four weeks, and Golden Week in early October, which accounts for a shorter but still meaningful disruption. Projects that run into either of these windows should expect delays unless they’ve been planned around them well in advance. A factory that’s running hard to finish orders before the New Year shutdown may not be giving your project the attention it deserves. A factory returning from holiday is clearing a backlog. Neither is the ideal moment to be expecting rapid progress.
A note on the difference between calendar time and working time
One nuance worth understanding early is that the time frames above refer to calendar time, not working time. A six-week sampling phase doesn’t mean six weeks of continuous activity. It means a sequence of steps — design file review, tooling production, component sourcing, assembly, finishing, shipping the sample to you — each of which has its own lead time, and many of which involve waiting for inputs from either side before the next step can begin.
This is why communication rhythm matters so much throughout the process. Every day a decision sits unanswered is a day added to the calendar — even if the factory’s actual working hours on your project were perfectly efficient. The projects that run smoothly are almost always the ones where both sides are responsive, organised, and proactive about keeping things moving.
Stage One — Initial Inquiry and Quotation (Weeks 1–2)
Every project starts with a conversation. But how that conversation begins has a surprisingly large effect on how the rest of the project unfolds — not just on the speed of the quote, but on the quality of the entire working relationship from that point forward.
What you need to bring to the first contact
A factory can only quote what you’ve described. The more precisely you describe it, the more useful the quote will be — and the less time gets spent going back and forth on clarifications that should have been included in the original brief.
At a minimum, your first inquiry should cover:
Watch type and general specifications. Is this a quartz or mechanical watch? What’s the approximate case diameter and thickness? Round case or a different shape? What water resistance rating are you targeting, if any? What movement brand or grade are you considering — Japanese, Chinese, or Swiss?
Materials. What do you have in mind for the case material — 316L stainless steel, titanium, something else? What about the crystal — mineral glass or sapphire? Strap or bracelet, and in what material?
Dial and finishing. Do you have design references, even rough ones? What kind of surface finish are you thinking about for the case — brushed, polished, PVD-coated, DLC? Any applied elements on the dial, or printed only?
Quantity. What’s your anticipated order volume for the first run? This affects unit pricing, MOQ viability, and the factory’s assessment of whether the project makes commercial sense for them.
Timeline. When do you need finished goods? Working backward from your target date gives the factory context for whether your expectations are realistic, and surfaces any conflicts with their production schedule early.
You don’t need to have every detail locked down at this stage — that’s what the design confirmation process is for. But the more complete your brief, the more accurate the quote, and the more seriously a professional factory will take the inquiry.
What the factory is doing during this stage
On the factory side, a quotation isn’t just a price calculation. A thorough factory is doing several things simultaneously when they receive your inquiry.
They’re assessing the technical feasibility of what you’ve described — whether your specifications are achievable, whether any elements raise manufacturing challenges worth flagging upfront, and whether there are components or materials in your brief that they don’t currently work with and would need to source.
They’re checking component availability and pricing. Movement costs fluctuate. Certain materials or surface treatments have lead times that need to be factored in. A factory that’s quoting responsibly is building those variables into the number they give you, not ignoring them.
They’re evaluating the commercial fit. Factories have production capacity constraints, specialisations, and minimum thresholds that determine which projects they take on. A professional factory that decides early on that a project isn’t the right fit for them is doing you a favour — better to know now than three months into a sampling process.
What a good quotation actually looks like
A quotation from a professional OEM watch factory should be a substantive document, not a single line price. It should include:
- Unit price broken down by component category where possible — case, movement, crystal, strap, dial, packaging
- MOQ and the pricing at different volume tiers if applicable
- Tooling costs, if any bespoke tooling is required for your design
- Sampling costs and the number of sample rounds included
- Estimated lead time for sampling and for production
- Payment terms — typically a deposit percentage at order confirmation, balance before shipment
- Validity period for the quote
If a factory sends you a one-line price without any of this context, treat it as a starting point for further questions rather than a complete picture. The detail in a quotation tells you something about how the factory operates — factories with mature processes document things thoroughly, because they’ve learned that vague agreements create problems down the line.
The most common reason this stage takes longer than it should
In the vast majority of cases, a delayed or unhelpful quotation traces back to an incomplete or ambiguous brief. When a factory has to ask multiple rounds of clarifying questions before they can quote, the timeline stretches — and more importantly, the quality of the eventual quote is often still imprecise because the full picture never fully came into focus.
The fix is straightforward: spend more time on the brief before you send it. If you have reference images, include them. If you have a rough sketch or a mood board, attach it. If you’ve been looking at specific competitor products and have a sense of what you like and don’t like about them, say so. The more clearly you can communicate your vision at the inquiry stage, the more efficiently the entire project moves from that point forward.
One more practical note: send your inquiry during the factory’s business hours if possible, and follow up if you haven’t received a response within three to five business days. Professional factories are generally responsive, but inboxes get busy and first contacts occasionally get missed. A polite follow-up is entirely normal and expected.
Stage Two — Design Confirmation and Sampling (Weeks 3–12)
If there’s one stage in the entire OEM process that deserves the most attention, the most patience, and the most careful decision-making — it’s this one.
Sampling is where your watch goes from a concept described in a brief to a physical object you can hold in your hand. It’s also where the majority of timeline overruns originate, where the most consequential decisions get made, and where the gap between a well-managed project and a poorly managed one becomes most visible.
Understanding what actually happens during this stage — and what your role in it is — is probably the single most useful thing you can do to set a watch project up for success.
What happens first: design confirmation
Before any physical sample is produced, the factory needs to work from a confirmed design. This doesn’t necessarily mean you need to arrive with finished CAD files — a professional OEM factory will typically have an in-house design or engineering team that can translate a detailed brief, reference images, and sketch concepts into production-ready technical drawings.
What it does mean is that the design needs to reach a point of genuine agreement before tooling or component sourcing begins. Every element that will appear in the physical sample — case dimensions, dial layout, hand style, crown position, lug shape, strap attachment, logo placement, surface finish specifications — should be documented and approved in writing before the factory commits to producing anything.
This step gets skipped or rushed more often than it should. Founders who are eager to see a physical sample sometimes push to move quickly past the design confirmation stage, only to receive a sample that doesn’t match what they had in mind — because what they had in mind was never fully articulated. A thorough design confirmation process at the front of this stage saves significantly more time than it costs.
Tooling: the step that surprises most first-time buyers
If your design requires any bespoke components — a custom case shape that doesn’t match an existing mold, a dial with specific cutouts or layering, a custom crown or pusher design — the factory will need to produce tooling before the first sample can be made.
Tooling is the process of creating the physical molds and dies used to manufacture those bespoke components. It takes time — typically two to four weeks for a standard watch case mold — and it costs money that is usually charged separately from the unit price and the sampling fee. Tooling costs for a new watch case can range from a few hundred to several thousand dollars depending on the complexity of the design and the material being worked with.
There are two things worth understanding about tooling. First, it is a one-time cost — once the tooling exists, it can be used across multiple production runs, so the per-unit impact diminishes with volume. Second, tooling modifications are possible but not free — if you decide after seeing the first sample that you want to change the case shape, the lug width, or any other element that the tooling was built to produce, there will be an additional cost and a delay while the tooling is revised.
This is one of the strongest arguments for investing time in the design confirmation stage. Changes made on paper before tooling is produced cost nothing but time. Changes made after tooling exists cost money.
Component sourcing runs in parallel
While tooling is being developed, the factory is also sourcing the components that don’t require bespoke production — movements, crystals, gaskets, crown components, and strap hardware. This sourcing process runs largely in parallel with the tooling phase, which is part of how professional factories compress the overall sampling timeline.
The variable to watch here is movement availability. Watch movements — particularly popular Japanese movements like the Miyota 8215 or 9015, or Swiss-made options — can have lead times of their own, especially during periods of high industry demand. A factory that checks movement availability at the quotation stage and flags any supply constraints early is demonstrating the kind of proactive supply chain management that matters significantly when you’re working to a deadline.
The first sample arrives — and it probably isn't perfect
This is the moment most founders have been looking forward to, and it’s also the moment where realistic expectations matter most.
A first sample is a proof of concept, not a finished product. Its purpose is to demonstrate that the design is achievable, to identify any technical or aesthetic issues that need to be resolved before production, and to establish a physical reference point for further refinement. It is almost never exactly right on the first attempt — and a factory that tells you to expect perfection from the first sample is either being optimistic or inexperienced.
What you should look for in a first sample is not perfection, but direction. Does the case shape capture the proportions you were after? Does the dial layout read the way you intended? Is the movement performing within an acceptable accuracy range? Are there obvious finishing issues that need to be addressed, or aesthetic elements that need to be reconsidered?
The answers to these questions form the basis of your feedback for the next round.
How to give sample feedback that actually moves things forward
This is a skill that sounds obvious but makes an enormous practical difference. Vague feedback produces slow, expensive results. Specific feedback produces faster, more accurate revisions.
Vague feedback sounds like: “The dial doesn’t feel quite right.” or “Can you make it look more premium?”
Specific feedback sounds like: “The hour markers are sitting 0.3mm too close to the rehaut — please increase the spacing. The sunburst finish on the dial is reading too dark in natural light — we’d like to see it two shades lighter. The crown knurling feels too fine for comfortable grip — please increase the ridge depth.”
The difference is that specific feedback gives the factory’s engineers something concrete to act on. Vague feedback requires them to interpret what you mean — which introduces the possibility of misinterpretation and another round of back-and-forth before a revised sample can be produced.
A useful practice is to photograph the sample in detail, annotate the images directly with your comments, and send them alongside a written summary. This leaves no room for ambiguity and creates a documented record of what was requested, which protects both sides if there’s any later disagreement about whether a change was communicated.
How many rounds of sampling should you expect?
For a moderately complex OEM watch project, two to three rounds of sampling is typical. A straightforward project with clear specifications and fast decision-making can sometimes reach approval in a single round. A more complex project with multiple design revisions, material substitutions, or significant aesthetic changes can run to four or five rounds.
Each additional round of sampling adds time — typically two to four weeks per round, accounting for the factory’s production time and international shipping in both directions. This is why the decisions made at the design confirmation stage and the quality of feedback given after each sample have such a significant impact on the overall project timeline.
A project that reaches sample approval in two rounds and a project that requires five rounds might have identical production and shipping timelines, but arrive at launch six to eight weeks apart — entirely because of how efficiently the sampling phase was managed.
Stage Three — Sample Approval (Weeks 10–16)
Sample approval sounds like a formality. In practice, it’s one of the most consequential decisions in the entire project — and one of the most commonly rushed.
The moment you sign off on a sample, you’re setting the production benchmark. You’re telling the factory: make me several hundred of these, to this standard. Everything that comes off the production line will be measured against what you approved. If the approved sample has a flaw you didn’t notice, or an element you weren’t quite happy with but decided to overlook because you were eager to move forward, that flaw and that element will be replicated across every unit in your order.
This is the stage that rewards slowness. Not indefinite delay — but genuine, thorough evaluation before committing.
What to check when the sample arrives
When a pre-production sample lands on your desk, the instinct is to look at the overall impression first — and that impression matters. But a thorough evaluation goes considerably further than a general sense of whether it looks good.
Case and construction
Check the case dimensions against your approved specifications. Measure the lug width, the case diameter, and the case thickness. Examine the finishing — is the brushed surface consistent across all brushed areas, with no crossover onto polished surfaces? Are the edges crisp and even? Check the caseback fit and the crown action — does it screw down smoothly and fully? Does it pull out to the correct positions for setting the time?
Dial and hands
Look at the dial under different lighting conditions, including natural light. Printing quality, colour accuracy, and finish consistency are all best assessed in conditions close to how the watch will actually be seen. Check the alignment of any printed elements — indices, text, logos. Check the hand fit — are the hands centred on the dial, and do they clear the dial surface and each other without catching?
Movement performance
Wind or charge the movement fully and run it for at least 72 hours before drawing any conclusions about accuracy. A quartz movement should be losing or gaining no more than ±15 seconds per month under normal conditions. A mechanical movement’s acceptable range is wider but should still be within the tolerance you specified. Note the rate at multiple positions — dial up, dial down, crown up — since positional variance is normal but should be within an acceptable range.
Water resistance
If your watch carries any water resistance rating at all — even a basic splash resistance claim — do not rely on visual inspection of the seals. Water resistance needs to be physically tested. An air pressure test at the rating you specified is the minimum standard. If you don’t have access to testing equipment, consider sending the sample to a third-party testing lab or a local watchmaker with the appropriate equipment before approving it. This is not an optional check for a watch that will be sold with any water resistance claim.
Strap and hardware
Check the strap fit at the lugs — is it secure without play? Does the buckle or clasp operate smoothly? For a folding clasp, does it engage and release cleanly? Check the strap material against your specification — colour, texture, thickness, and any stitching quality if applicable.
Logo and branding elements
Check the logo placement, size, and rendering against your approved artwork. Look at the caseback engraving or printing if applicable. Check that any text — brand name, model name, water resistance designation, movement type — is correct, correctly positioned, and rendered consistently.
The temptation to approve something that isn't quite right
Here is the honest truth about sample approval: there will almost always be at least one element of the sample that isn’t exactly what you wanted. Maybe the dial colour is slightly off. Maybe the hand finish isn’t quite as refined as your reference image. Maybe the crown action feels a little stiffer than you’d like.
And at this point in the project — after weeks of development, after multiple rounds of sampling, after the investment of time and money that has already gone in — the temptation to approve it anyway is genuinely powerful. You want to move forward. You’ve been patient. The watch is mostly right. Surely the small things won’t matter once it’s on the wrist.
This reasoning is responsible for a significant proportion of the product quality issues that brand founders end up dealing with after their first production run. The small things do matter. They’re what customers notice. And they’re what reviewers write about.
The right approach is to be honest with yourself about what you’re approving. If the issue is minor and cosmetic — a degree of variation that’s within normal manufacturing tolerance and that you can live with — then approving and moving forward is reasonable. If the issue is something that genuinely doesn’t meet your standard, or that you know will bother you every time you see the product, it is worth one more round of revision.
The cost of that extra round is real. But it is smaller than the cost of receiving several hundred units of a product you’re not fully proud of.
Formalising the approval
Sample approval should not happen verbally or through a casual message. It should be a documented exchange — a written confirmation that explicitly states which sample version has been approved, that this sample represents the production standard, and that any deviations from this standard in the production batch will be subject to the defect resolution process outlined in your purchase agreement.
This documentation protects you. It gives you a clear reference point if the production quality doesn’t match what you approved. It also gives the factory clear direction — there’s no ambiguity about what standard they’re manufacturing to, which reduces the risk of quality drift during a long production run.
Some factories will provide a formal sample sign-off form. If yours doesn’t, create your own — a simple written confirmation with the sample version number, date, your name, and a brief description of any specific elements to pay particular attention to during production is sufficient.
What happens after approval
Once you’ve formally approved the sample, two things need to happen in parallel to keep the project moving: the production deposit needs to be processed, and the factory needs to lock in the production schedule.
Payment processing — particularly international wire transfers — can take several business days to clear. Some founders wait until the transfer is confirmed before notifying the factory, which adds unnecessary delay. A better approach is to notify the factory as soon as you’ve initiated the transfer and provide a remittance confirmation. This allows them to begin production scheduling immediately rather than waiting for the funds to appear.
Production scheduling matters because most factories are managing multiple orders simultaneously. The sooner your project is slotted into the production queue after sample approval, the sooner it gets started — and in a busy factory, the difference between being scheduled for next week and being scheduled for three weeks from now can come down to how quickly the administrative steps were completed after approval.
Stage Four — Mass Production (Weeks 14–20)
With the sample approved and the deposit received, the factory moves into mass production. For many brand founders, this stage feels like the calm after the storm — the hard decisions have been made, the design is locked, and the process is now in the factory’s hands.
That sense of calm is largely warranted. But “in the factory’s hands” doesn’t mean you disengage entirely. The brands that receive the best production outcomes are the ones that stay appropriately connected throughout this phase — not micromanaging, but present enough to catch problems early and keep communication flowing in both directions.
What actually happens during production
Mass production is not a single continuous activity. It’s a coordinated sequence of sub-processes that run across different workstations, different teams, and in some cases different suppliers, all converging toward a finished unit.
The process begins with a production setup phase — sometimes called a first article inspection — where the line is configured to produce your specific watch and the first units off the line are checked against the approved sample before full-speed production begins. A factory with mature processes treats this step seriously, because catching a setup error at the start of a run is dramatically less costly than discovering it after five hundred units have been assembled.
From there, production moves through component assembly — movement installation, dial fitting, hand setting, case assembly, crown and gasket installation — followed by functional testing at key stages, surface finishing where applicable, strap or bracelet attachment, and final unit preparation before the goods move to the quality control stage.
Throughout all of this, the factory’s in-process quality control team should be working alongside the production line — checking for consistency in finishing, verifying movement function at assembly, and pulling units that fall outside specification rather than allowing them to continue down the line.
How to stay appropriately connected during production
The right level of engagement during mass production is somewhere between daily check-ins and complete silence. A useful rhythm for most projects is a progress update every one to two weeks, with photos or videos of work in progress at key milestones — components received and checked, first assembled units, finishing completed.
Most professional factories are entirely willing to provide these updates if you ask for them at the start of the production phase. The key is to establish this expectation proactively rather than requesting updates reactively when anxiety sets in three weeks into a quiet period.
What you’re looking for in these updates isn’t a guarantee that everything is perfect — that’s what QC is for. You’re looking for confirmation that production is progressing on schedule, that there are no supply or capacity issues developing, and that the visual quality of units in progress looks consistent with the approved sample. If something in an update photo doesn’t look right, raising it early gives the factory the opportunity to address it before it becomes a systemic problem across the full batch.
What can cause production delays
Production delays are not inevitable, but they’re common enough that building some buffer time into your planning is simply prudent. The most frequent causes are worth knowing in advance.
Component supply disruptions. Even with components sourced during the sampling phase, supply chain variability means that the specific movement, crystal, or strap hardware specified for your order may face availability constraints by the time mass production begins. A good factory monitors this proactively and flags issues early. A less attentive one discovers the problem mid-production. Ask upfront whether all components for your order have been confirmed and reserved.
Production capacity conflicts. Factories manage multiple orders simultaneously, and production schedules are dynamic. An unexpectedly large order from another client, or a quality issue on a parallel project requiring rework, can compress the time available for your run. This is less of a problem with factories that have substantial production capacity and less of a concern when your order is scheduled well in advance — another argument for moving quickly through the approval stage.
Quality-related rework. If the factory’s in-process QC identifies a batch of units that don’t meet specification — a finishing inconsistency, a movement batch with higher-than-acceptable variance — the affected units need to be reworked or replaced before the order can be completed. This is actually a sign of a factory’s QC system working as intended, but it does add time. A factory that never has any rework is either unusually perfect or not checking carefully enough.
Raw material or finishing delays. Certain surface treatments — PVD coating, DLC, specific plating processes — are sometimes performed by specialist third-party suppliers rather than in-house. If your watch involves any of these processes, the scheduling of that external step is a variable worth confirming explicitly.
The Chinese manufacturing calendar — planning around holidays
No discussion of production timelines would be complete without addressing the two periods in the Chinese manufacturing calendar that have derailed more brand launch plans than any other single factor.
Chinese New Year is the more significant of the two. The holiday itself typically falls in late January or early February, but its effect on production schedules begins well before the official dates and continues well after. In practice, factories wind down operations in the two weeks prior to the holiday as workers begin travelling home, and spend the first week or two after the holiday returning to full capacity as the workforce reassembles. The effective dead zone runs for approximately three to four weeks.
The implications for project planning are significant. Any order that needs to be completed before Chinese New Year requires earlier-than-usual production scheduling — factories are running hard to clear their books, which means capacity is tight and your project is competing with many others for priority. Any order placed in November or December with a pre-CNY delivery expectation is almost certainly carrying unrealistic timeline assumptions unless those conversations happened very early.
Orders that span the holiday period should be planned with a minimum of four weeks of buffer built in around the CNY dates. And orders placed in late January or February — right as the holiday is beginning or just ending — should expect a slow start to production as factories return to operational rhythm.
Golden Week in early October is a shorter disruption — typically one week of official holiday with a few days of reduced capacity on either side — but it’s worth accounting for in tight timelines. A project with a late September completion target that doesn’t account for Golden Week is a project that may miss that target.
The simplest planning principle is this: know the dates, build the buffer, and have the conversation with your factory about how the holiday schedule affects your specific order well before it becomes relevant.
Payment at this stage
Production typically requires a deposit of 30% to 50% of the total order value at the point of production commencement, with the balance due before shipment. Some factories have slightly different structures, but this is the most common arrangement.
It’s worth confirming the exact payment schedule in your purchase agreement before production begins, so there are no surprises when the balance invoice arrives. Delays in processing the balance payment — which typically needs to clear before the factory will release goods for shipment — are one of the more common and entirely avoidable causes of final-stage timeline slippage. Having the payment ready to process as soon as the pre-shipment inspection is passed removes this as a variable.
Stage Five — Quality Control, Packaging, and Shipment (Weeks 18–24)
The watches are assembled. The production run is complete. You’re close — but not quite there yet. The final stage of the process covers the steps between a finished production batch and goods that are actually on their way to you, and it involves more moving parts than most first-time buyers expect.
This is also the stage where a significant amount of the final quality outcome is determined. A strong QC process at this point catches problems before they reach your customers. A weak one — or the absence of one — means those problems find their way into your customers’ hands instead.
The quality control process
A professional OEM watch factory runs quality control at three distinct levels, and the final stage is where all three converge to produce the outgoing inspection that clears units for packaging and shipment.
Incoming quality control (IQC) happens at the start of the production process, when components arrive from suppliers. Movements are checked for accuracy and function. Cases are checked for dimensional conformity and finishing quality. Crystals are checked for clarity and fit. This step prevents defective components from entering the production line in the first place — which is considerably more efficient than catching defects in finished units.
In-process quality control (IPQC) happens throughout assembly. At defined checkpoints — after movement installation, after case assembly, after strap attachment — units are inspected against the approved sample standard. Units that fall outside specification are pulled from the line for rework or rejection rather than being allowed to continue to the next stage.
Final quality control (FQC) is the outgoing inspection that takes place on completed, finished units before they are packaged. This is the comprehensive check that covers everything: dimensional conformity, finishing consistency, movement performance, water resistance, strap and clasp function, branding accuracy, and overall aesthetic quality against the approved sample.
A factory with a genuine QC system should be able to provide you with documentation from the FQC stage — an inspection report that records the sample size checked, the criteria applied, the pass/fail results, and the overall defect rate for the batch. This report is not just reassurance — it’s a production record that matters if any quality issues surface after delivery.
Third-party inspection — when it's worth arranging
For most standard orders with a factory you have an established relationship with, the factory’s own FQC documentation is a reasonable basis for releasing the goods. But there are situations where arranging an independent third-party inspection makes commercial sense.
If this is your first order with a factory and you haven’t yet established confidence in their QC process, a third-party inspection provides an independent verification of the batch quality before you commit the balance payment and accept the goods. If your order is large enough that a quality failure would represent a significant financial exposure, the cost of an independent inspection — typically a few hundred dollars for a standard visit — is a modest insurance premium against that risk. And if you’re supplying into a retail channel or a corporate client with specific quality expectations, an independent inspection report can be a useful piece of documentation for that relationship.
Companies like SGS, Bureau Veritas, and Intertek all offer pre-shipment inspection services in China. The process typically involves an inspector visiting the factory, randomly sampling a statistically significant number of units from the batch, and producing a report against your specified criteria. Coordinating this needs to happen a week or so before the planned ship date to allow time for the inspection to be completed and any identified issues to be addressed before goods leave the factory.
Packaging confirmation
Branded packaging — boxes, inserts, hangtags, warranty cards, and any other collateral that ships with the watch — is often produced on a separate timeline from the watches themselves, and it’s an element that first-time buyers frequently underestimate in terms of lead time and complexity.
Packaging artwork needs to be supplied and approved before production of the packaging materials can begin, and this step should ideally be running in parallel with the watch production phase rather than starting after the watches are done. A packaging production timeline of three to four weeks is typical for custom-printed boxes and inserts, and longer for more complex packaging constructions.
If the packaging isn’t ready when the watches are, you have a finished production batch sitting in the factory waiting to be packed — which adds time and, depending on your payment terms, may complicate the shipment release process.
The simplest way to avoid this is to confirm the packaging specification and initiate the artwork approval process at the same time as you confirm the production order, not as an afterthought once production is underway.
Choosing between air freight and sea freight
Once goods are packed and ready to ship, you have a choice between air freight and sea freight that involves a real trade-off between speed and cost.
Air freight typically delivers goods to major international destinations in five to ten business days from the point of departure. It is considerably more expensive than sea freight on a per-kilogram basis, but for smaller orders — up to a few hundred units — the absolute cost difference is often manageable, and the speed advantage is significant. If you’re working to a tight launch timeline or need to replenish inventory quickly, air freight is frequently the right call.
Sea freight takes considerably longer — typically four to six weeks from a Chinese port to destinations in Europe or North America, plus inland transport time at the destination end. The cost per unit is substantially lower, which makes it the practical choice for larger orders where the total freight cost on an air shipment would be prohibitive. For a first order where the timeline has been planned appropriately, sea freight is often the economically sensible option.
A hybrid approach — shipping a portion of the order by air to meet an initial launch commitment while the bulk of the inventory follows by sea — is worth considering for launches with a hard date and a large initial order quantity.
Customs clearance — the details that matter
International shipments of watches involve customs procedures at the destination that add time and, if not handled correctly, can create delays that are both frustrating and avoidable.
A few specifics worth knowing:
HS code accuracy. Watches have specific Harmonised System classification codes that determine the applicable duty rate at your destination. Using an incorrect HS code can result in customs holds, additional documentation requests, or duty assessments that differ from what you planned for. Confirm the correct HS code for your product with your customs broker before the shipment is prepared.
Commercial invoice detail. The commercial invoice accompanying the shipment needs to accurately describe the goods — quantity, unit value, country of origin, and a description that matches the HS code classification. Discrepancies between the invoice and the physical goods are one of the most common causes of customs delays.
Duties and import taxes. Watch imports are subject to varying duty rates depending on the destination country, the watch’s country of origin, and any applicable trade agreements. These costs should be factored into your landed cost calculations from the beginning of the project, not discovered at the customs clearance stage. A freight forwarder or customs broker familiar with watch imports in your target market is a worthwhile resource.
CE and other compliance markings. If you’re importing into the EU or certain other markets, there may be specific compliance requirements that apply to your product. These are worth confirming well before the shipment is prepared, as retroactive compliance documentation can create significant delays.
The balance payment and goods release
Under most factory payment terms, the balance of the order value — typically the remaining 50% to 70% after the production deposit — is due before the factory releases goods for shipment. This payment needs to clear before the freight forwarder can pick up the goods, which means any delay in processing the balance directly delays the ship date.
The practical advice here is the same as with the production deposit: have the payment ready to process as soon as the pre-shipment inspection is passed and you’re satisfied with the batch. Waiting until after the goods are packed and sitting in the freight forwarder’s hands before initiating the transfer adds unnecessary days to the final stage of a process you’ve been managing for months.
The Hidden Timeline Killers — What Nobody Warns You About
Every stage we’ve covered so far describes how the process works when things go broadly as planned. But experienced sourcing professionals will tell you that the official timeline and the actual timeline are rarely identical — and the gap between them is almost never explained by the obvious variables.
The delays that genuinely derail projects don’t usually come from dramatic failures. They come from accumulations of small friction points that nobody flagged as problems until they’d already added up to weeks of lost time. Here are the ones that show up most consistently — and that almost nobody mentions to first-time buyers before they discover them firsthand.
Communication lag — the invisible time tax
This one sounds mundane, but its impact on project timelines is substantial and almost universally underestimated.
China Standard Time sits eight hours ahead of Central European Time and thirteen to sixteen hours ahead of North American time zones. In practice, this means that a question sent at the end of your working day may not receive a response until the following morning at the earliest — and if the response raises a further question, you’ve just consumed two full calendar days on an exchange that took fifteen minutes of actual human attention.
Multiply this across a project with dozens of decision points, and the cumulative time cost is significant. A project where both sides respond within the same business day moves through the process noticeably faster than one where responses routinely take 24 to 48 hours. Over the course of a full OEM project, the difference can easily account for two to four weeks of additional calendar time.
The practical mitigation is twofold: establish a clear communication rhythm with your factory contact at the start of the project, including expected response time on both sides, and whenever possible, batch your questions and feedback into single comprehensive messages rather than sending multiple short messages that each require a separate response.
Design changes after sampling begins — the reset button nobody wants to press
This one has cost more brand founders more time and money than almost any other single factor in the OEM process.
The dynamic works like this: the first sample arrives, and alongside the feedback you expected to give, you realise that something more fundamental isn’t right. Maybe the case proportions aren’t quite landing. Maybe you’ve reconsidered the dial layout. Maybe you’ve seen a competitor’s product in the intervening weeks and it’s changed your thinking about where you want to position the design.
Any change that affects a component already in production — a tooled case, a dial printing plate, a custom strap hardware die — doesn’t just require a revised sample. It potentially requires new tooling, new setup costs, and a restart of the component sourcing process for the affected elements. What presents itself as a design refinement can, depending on what’s being changed, add four to eight weeks and several hundred to several thousand dollars to the project.
The way to avoid this is to do the hard thinking about the design before sampling begins, not during it. Reference images, competitive analysis, detailed brief reviews with your factory contact, internal sign-off from everyone with a stake in the product — all of this should happen before a single piece of tooling is ordered. The sampling phase should be about refinement, not reconsideration.
Payment processing delays — the bottleneck nobody plans for
International wire transfers between different banking systems take time. Not always, but often enough that counting on same-day or next-day clearance is a mistake.
A transfer that originates from a US or European bank account to a Chinese factory’s account typically takes two to five business days to clear. Some transactions clear faster. Some hit compliance review flags that extend the timeline considerably. Currency conversion, correspondent bank routing, and transaction size all affect processing speed in ways that are difficult to predict.
The problem is that factories generally don’t begin the next phase of work until the relevant payment has cleared. This is entirely reasonable from the factory’s perspective, but it means that a four-day payment delay at the production deposit stage is a four-day delay in the production start date. A similar delay at the balance payment stage is a four-day delay in the shipment release.
Over the course of a project with two or three payment milestones, payment processing delays alone can account for a week or more of total timeline slippage. The mitigation is straightforward: initiate payments as early as possible in the payment window, use a bank or payment service with a reliable track record for international transfers, and provide your factory with remittance confirmation immediately so they can begin work without waiting for funds to visibly clear.
Component availability surprises — when the supply chain moves without you
Watch movements, crystals, and certain hardware components are sourced from suppliers who operate on their own production and inventory cycles. A movement model that was readily available when you received your quotation may have a six-week lead time by the time mass production begins, either because of industry demand fluctuations or because the factory didn’t reserve stock at the time of quotation.
This is particularly relevant for popular Japanese movements — the Miyota 8215, the NH35, and similar calibres that many brands specify simultaneously. When demand spikes, lead times extend. A factory that proactively reserves movement stock at the point of order confirmation is managing this risk on your behalf. A factory that sources components reactively when production is scheduled to begin is leaving you exposed to supply variability that neither of you can fully control once it materialises.
Ask your factory directly, at the point of order confirmation: have the components for my order been reserved? If the answer is vague, push for specifics on movement availability in particular.
Artwork and file delivery delays — from your side
This one is worth including because it’s a delay that originates entirely with the client — which means it’s entirely within your control, and entirely avoidable.
Logo files, dial artwork, caseback engraving specifications, packaging design, and any other brand assets that need to be delivered to the factory for production all have their own internal approval processes on the client side. Revisions go through design teams. Sign-offs require stakeholder availability. Files end up in the wrong format and need to be revised.
None of this is unusual. All of it takes time. And every day that the factory is waiting for a final artwork file before they can produce a dial printing plate or commission packaging materials is a day added to the project timeline.
The discipline required here is simply to treat artwork delivery as a critical path item — something with a hard internal deadline that gets the same urgency as the external milestones. Build the artwork approval process into your project plan from the beginning, assign clear internal ownership, and deliver files to the factory earlier than you think you need to.
Scope additions mid-project — the cost of "while we're at it"
A project that starts as a single watch model sometimes grows during the development phase. An additional colourway gets added. A second strap option is requested. A new dial variant is introduced partway through sampling. Each of these additions is individually small and individually reasonable. Collectively, they can significantly complicate the production schedule and extend the overall timeline.
Every addition to the project scope mid-process reintroduces questions that had already been answered for the original specification — component sourcing, tooling requirements, sampling, quality benchmarks. A factory managing a project that keeps expanding its scope is a factory that is constantly readjusting its production planning rather than executing against a fixed plan.
This doesn’t mean the scope should never change. It means changes to the scope should be deliberate and timed thoughtfully — consolidated into a single revision rather than introduced incrementally, and confirmed in writing so the full impact on timeline and cost is understood before the change is made.
A Practical Timeline Planner
Everything covered so far has been about understanding the process. This section is about applying that understanding to your specific situation — working out what the timeline actually looks like for your project, and building a plan that accounts for the real variables rather than the optimistic ones.
The core planning principle: work backwards from your launch date
The most common timeline mistake in watch product development isn’t miscalculating a single stage — it’s starting the planning process from the wrong end. Most founders think forward: I’ll contact the factory in January, sampling will take a couple of months, production will follow, and I’ll launch in the spring. The problem with this approach is that it accumulates optimistic assumptions at every stage, and by the time those assumptions meet reality, the launch date has already been missed.
The more reliable approach is to work backwards from a fixed point. Start with the date you need goods in your hands — your launch event, your retail partner’s receiving window, your peak season inventory deadline — and map the required milestones backward from there.
Working backwards from a target in-hands date, a standard OEM project timeline looks like this:
- Goods in hands (Week 0 from your perspective)
- Goods depart factory / customs clearance: 1–2 weeks prior (air) or 5–7 weeks prior (sea)
- Pre-shipment inspection and balance payment: 1 week before departure
- Mass production complete / FQC: 4–6 weeks before departure
- Mass production commences: 4–6 weeks before completion, requiring deposit cleared
- Sample approved / production deposit initiated: 2–4 weeks before production commences
- Sampling phase: 6–10 weeks before sample approval
- Design confirmation: 1–2 weeks before sampling commences
- Initial inquiry and quotation: 1–2 weeks before design confirmation
Adding these up in the most optimistic realistic scenario — not the best case, but a genuinely achievable timeline with good communication and no significant complications — puts the total at approximately 20 to 26 weeks from first contact to goods in hand.
That’s five to six months. If your launch date is in October, your first factory conversation should be happening no later than April — and ideally in March.
A week-by-week reference timeline
The following is a representative project timeline for a moderately complex OEM watch — a standard round case with a custom dial, Japanese automatic movement, sapphire crystal, and branded leather strap. It assumes responsive communication on both sides and no major design revisions after the first sample round.
Weeks 1–2: Initial inquiry and quotation
First contact with factory. Brief submitted. Factory assesses feasibility and prepares quotation. Quotation reviewed and questions resolved. Commercial terms agreed.
Weeks 3–4: Design confirmation
Technical drawings reviewed and approved. Material specifications confirmed. Dial artwork and logo files delivered. NDA signed. Tooling order placed for custom case elements.
Weeks 5–8: Tooling and component sourcing
Case tooling produced. Movement and component stock reserved and ordered. Dial printing plate produced. Factory begins pre-production preparation.
Weeks 9–11: First sample production and shipment
First physical sample assembled. Sample shipped to client via express courier. Client receives and evaluates sample.
Weeks 12–13: Sample feedback and revision
Client provides detailed written feedback. Factory produces revised sample incorporating changes. Revised sample shipped to client.
Weeks 14–15: Sample approval
Client reviews revised sample. Minor remaining points addressed. Sample formally approved in writing. Production deposit initiated.
Weeks 16–17: Production deposit clears / production scheduling
Deposit confirmed received. Production slotted into factory schedule. Packaging artwork confirmed and packaging production initiated in parallel.
Weeks 18–21: Mass production
Full production run executed. In-process QC conducted throughout. Client receives progress updates at agreed intervals. Packaging produced and delivered to factory.
Week 22: Final QC and pre-shipment inspection
Completed batch undergoes full FQC. Inspection report produced. Third-party inspection conducted if arranged. Any minor rework completed.
Week 23: Balance payment and shipment preparation
Client initiates balance payment on receipt of QC report. Goods packed with branded packaging. Freight forwarder engaged. Shipment documentation prepared.
Week 24–25: Shipment and delivery
Goods depart factory. Air freight: goods arrive at destination within 5–10 business days. Sea freight: goods arrive at destination port 4–6 weeks after departure.
Adjusting the timeline for your specific situation
The reference timeline above is a useful starting point, but your project will have variables that affect it in both directions. Here’s how to adjust for the most common ones.
If your design requires significant new tooling — a completely custom case shape, a complex dial construction, bespoke hardware — add two to three weeks to the tooling and sampling phase. First samples for heavily tooled designs take longer to produce, and the revision stakes are higher because tooling modifications carry additional cost.
If you’re a fast decision-maker with pre-prepared assets — you have clear reference materials, your artwork is production-ready, your internal sign-offs happen quickly — you can reasonably compress the design confirmation and sample feedback stages by a week or two on each. Some projects with well-prepared clients have moved through the sampling phase in four to five weeks rather than eight to ten.
If your project spans Chinese New Year — identify the holiday dates for your project year and add four weeks of buffer around them. Don’t assume the factory can complete work right up to the holiday date — build the buffer in before the holiday, not after it.
If you’re shipping by sea to a distant market — add the full sea freight transit time to your delivery calculation. A six-week ocean transit from Shenzhen to Rotterdam means your goods need to leave the factory six weeks before your in-hands deadline, not one or two weeks.
If this is your first order with a new factory — add a week or two of buffer throughout the process to account for the learning curve on both sides. First projects with a new manufacturing partner have more communication overhead than subsequent ones, because both sides are still developing the working rhythms and mutual understanding that make later projects run more efficiently.
The buffer rule — and why it's not pessimism
Every project plan should include buffer time at each major stage transition. Not because things will definitely go wrong, but because the cost of buffer time is low and the cost of a missed launch date is high.
A week of buffer between sample approval and production commencement costs you nothing if the project runs smoothly — production simply starts a week earlier than the buffer assumed. But if a payment takes four days longer to clear than expected, or a minor sample revision requires an additional week, that buffer absorbs the delay without affecting the overall launch date.
Building buffer into a project plan isn’t pessimism — it’s the difference between a plan that survives contact with reality and one that doesn’t. The brands that consistently hit their launch dates aren’t the ones that plan for everything to go perfectly. They’re the ones that plan for things to go mostly well, with enough room to handle the parts that don’t.
Plan the Timeline, Own the Outcome
There’s a version of the OEM watch manufacturing process that feels chaotic and unpredictable — where delays appear without warning, where launch dates slip repeatedly, where the factory always seems to be the problem. That version is real, and it happens to brands every day.
But it’s not inevitable. And in most cases, it’s not primarily the factory’s fault.
The brands that move through this process smoothly are almost never the ones with the most experienced sourcing teams or the most sophisticated supplier relationships. They’re the ones that came in with realistic expectations, prepared their briefs carefully, made decisions quickly and documented them clearly, and built plans that had enough room to absorb the ordinary friction of international manufacturing without falling apart.
The process itself is predictable, if you take the time to understand it. Every stage has a logic. Every delay has a cause. Every cause has either a prevention or a mitigation, and most of them are within your control once you know to look for them.
What this guide has tried to give you is that understanding — a clear picture of what happens at each stage, what your role in it is, where the common failure points are, and how to plan in a way that gives your project the best realistic chance of hitting its targets. Whether this is your first OEM order or your fifth, the fundamentals don’t change: clarity upfront, good communication throughout, and honest planning from beginning to end.
At Romlicen, the timeline framework described in this guide reflects how we actually work with our clients. We share updates at every production milestone. We flag supply chain variables before they become problems. We push back on unrealistic timelines rather than agreeing to them and delivering late. And when something unexpected comes up — because in manufacturing, something occasionally does — we communicate about it immediately rather than hoping it resolves itself before you notice.
If you’re planning a custom watch project and want to understand what the timeline looks like for your specific design and order requirements, we’re happy to walk you through it in detail. A realistic timeline conversation at the start of a project is one of the most valuable things we can offer — and it costs nothing.
