Your watch, your rules.

A Seiko mod is a modified watch that uses an authentic Seiko movement, combined with third-party high-quality parts. Most of our watches come in stainless steel with sapphire crystal.

When you place an order, we order the parts for your design right away. The entire process usually takes about 20 days: parts normally arrive within 2–3 weeks (including weekends). When we receive the parts, we build the watch the same day and ship it as soon as possible after assembly. Watches in stock from time to time ship faster.

Absolutely. Send us an email with your order number and full name after ordering, stating your desired design or that you want to remove the logo. You can also leave a note at checkout, or contact us before ordering.

Every watch from our workshop comes with a free 1-year warranty covering manufacturing defects and operating problems under normal use. You can also purchase a 1-year extension. Warranty does not cover scratches, damage from opening the watch, or water-resistance issues — our watches are not designed for swimming or diving.

Check our reviews on Trustpilot and on our website — we have a lot of positive customer feedback. We also have over 10,000 followers on Instagram. Payments run through secure providers, so you can shop with confidence.

We push prices down as much as we can. We believe many comparable watches are overpriced because shops bundle extras (like extra straps) into the price. We let you choose what you want, so you only pay for what you actually need.

Yes. We source from suppliers who sell authentic Seiko movements. Once you receive your watch, you can have it confirmed by any watchmaker. If you believe the movement is not genuine, you can return the watch within 14 days of receipt.

Yes — all our watches are built by hand.
