People Behind Your Watch
Behind every USAMODWATCH timepiece is a small team of watchmakers who take pride in what they do.
Each one brings steady hands, sharp focus, and years of experience to the bench — turning raw components into precise, living mechanisms.
We build, test, and assemble every piece by hand. Driven by a shared belief that true quality can’t be rushed or automated.
Our mission is simple: To keep the spirit of craftsmanship alive, creating watches that connect people not only to time, but to the hands that made it.
Any questions left?
What should you do if the DIY watch style you want isn’t listed on our website?
We carry the most complete selection of mod parts available anywhere—not all of them are listed online.
Feel free to contact us with your custom request via the Instagram or email links at the bottom of the page.
We’ll help you check availability and feasibility, including dial and caseback printing, bezel and dial swaps, and more.
What is the difference between USAMODWATCH and an authentic Seiko watch?
USAMODWATCH is an independent brand that hand-assembles every watch in the U.S. We use genuine Seiko movements and high-quality components to build Seiko mods that are both reliable and truly one-of-a-kind.
Each piece is carefully crafted to combine Seiko’s trusted performance with a unique design you won’t find anywhere else.
What’s the difference between automatic and quartz movement?
Automatic watches run on a spring-driven movement powered by your wrist’s motion. If not worn, they will stop after 41 hours, but just by wearing it again during your daily activities, it will automatically resume running.
Quartz watches are battery-powered and highly accurate. They offer convenience and precision, requiring minimal maintenance.
What’s the difference between Seiko mechanical movements (NH35, NH36, NH38, NH39, NH70)?
Each Seiko movement has a slightly different function and structure:
- NH35 – The most common and reliable automatic movement, with date display.
- NH36 – Similar to NH35 but adds a day-date function.
- NH38 / NH39 – No date, cleaner dial design, often used for minimal or open-heart styles.
- NH70 – A skeletonized version, showing the internal mechanics in motion.
All are automatic, self-winding, and built with Seiko’s precision — the main differences lie in display functions and visual design.
Can I wear it while swimming or showering?
No. Most of our watches are rated 5 ATM for everyday water resistance. However, we don’t recommend wearing it while showering or swimming. The conditions in those environments, such as water vapor, differ from accidental water exposure, and may affect the watch. Water damage is not covered under warranty.
How can you cancel an order if you are not satisfied?
• Before shipping: You can request a full refund within 48 hours.
• After shipping: Returns are accepted if the watch remains in original, resaleable condition.
• DIY custom watches are non-refundable, unless there are significant quality issues.
How does the lifetime free repair service work?
All our watches include lifetime free repair service. You only cover shipping and parts; we handle the craftsmanship. Simply contact us and send your watch in — our team will restore it with care.
