“Hey Seiko Mod Lover,admit it :”

Q: What is a Seiko Mod?

A Seiko Mod is a custom-built watch using genuine Seiko mechanical movements (like NH34 or NH35/36), combined with modified cases, dials, bezels, and hands.

Q: Can I customize a watch?

Yes! You can build your own Seiko mod using our online customization tool . Select every detail and we’ll hand-assemble it for you.

❌We’re NOT dropshippers.

❌No mystery parts.

❌No factory guesswork.

We’re just two watch modders building every piece by hand.Only 8–10 watches a day, so quality comes first.（Timing test paper with every NH34/35/72.）

No big marketing spend. No inflated prices — just fair, honest craftsmanship.

“Clients often ask why our prices are lower than other mod shops.”

“Here’s why —” Those “based” in small European countries?Often just virtual addresses for dropshippers — buying cheap, selling high, and covering high warranty/return rates.

That’s not us.

Small team. Big dedication.

If we’re busy, it may take a few extra days —worth every second.
