Buying a custom-built watch online is mostly a process problem, not a product problem. If you know what to ask for before you pay and what to check when the box arrives, the failure modes are predictable.
1. Start from a reference, not a photo
Send the factory reference number — 116610LV, 5711/1A-010, 15500ST — rather than a screenshot. Reference numbers pin down the case dimensions, dial colour, bracelet fitment and movement generation. A photo pins down nothing.
2. Ask which movement, and why
Two builds of the same watch can differ by 400 dollars purely on the calibre. Ask directly: which movement, what power reserve, and is it regulated before shipping. If the answer is vague, walk away.
3. Demand QC photos before dispatch
Not stock photos — photos of your actual unit, on a bench, with a time stamp. You want to see:
- Dial printing under magnification
- Date wheel alignment inside the window
- Rehaut engraving depth
- Bracelet end-link fitment against the lugs
- Caseback engraving and serial
- The watch running next to a timing machine readout
A seller who will not send these is a seller who has not looked at the watch.
4. Confirm the shipping method and insurance
Express with signature, insured, plain packaging. Ask what happens if customs seizes the parcel — the answer should be a replacement policy in writing, not “it won’t happen”.
5. Pay in a way that leaves a trail
Crypto and bank transfer are standard in this market. Keep the transaction hash or the transfer receipt, and make sure the order number appears in the payment reference.
6. Verify on arrival — the fifteen-minute check
- Weight. Put it on a kitchen scale. A 904L Submariner should be around 155 g. Ten grams light means a different case.
- Crown action. Unscrew, pull to position two and three. It should click positively, with no wobble.
- Date change. Set the time forward past midnight. The date should flip cleanly, not hang halfway.
- Bezel. Count the clicks. A Submariner bezel has 120; a sloppy 90-click bezel is a different assembly.
- Lume. Charge under a lamp for 30 seconds. It should glow evenly with no dark patches at the indices.
- Rate. Sync to a reference clock, wait 24 hours, measure the difference. Anything inside ±10 s/day is fine.
7. Know what is not covered
Water resistance is the honest limitation. A custom build is pressure-tested, but gaskets age and casebacks are not factory-sealed. Do not dive with it. Swim with a screw-down crown watch if you have had it tested in the last year — otherwise take it off.
8. Keep the paperwork
Keep the timing printout, the QC photos and the order confirmation. They are what a warranty claim is judged on, and they also help a watchmaker years later when the watch needs service.
What we do differently
We send timing printouts, bench photos and the expected weight with every order, and we will re-regulate a watch free within the first year. If you are unsure which build matches the reference you want, send it to us and we will tell you honestly whether we can build it well.
