FREQUENTLY ASKED QUESTIONS

What is a Seiko Mod?

A Seiko mod is a custom-built watch that begins with a reliable Seiko automatic movement and is enhanced with premium aftermarket components, often made from robust 316L stainless steel. Each timepiece is carefully hand-assembled, combining Seiko’s renowned precision with a design tailored to your personal style.

The purpose of Seiko modding is to make the aesthetics and craftsmanship of luxury watches more accessible—without counterfeits—by using only the finest materials such as sapphire crystals, ceramic bezels, and solid stainless steel cases. Whether you’re after a professional diver, a versatile GMT, or a refined dress watch, a Seiko mod allows you to create your dream timepiece with individuality and enduring quality at its heart.

Can I Design My Own Watch?

With our custom Seiko mod service, you can personalize every detail of your watch—from the bracelet, case, and dial to the hands and finishing touches. We even offer the option to add your own logo or initials for a truly bespoke design. If you’re ready to create a personalized Seiko mod watch, contact us on Instagram or via email to discuss your ideas directly with one of our expert watchmakers.
