FAQs
A “Seiko Mod” refers to a custom Seiko watch that has been altered to match an individual’s style or functional needs.
Modifications can be purely aesthetic, such as changing the dial, case, hands, or bezel, or functional, such as improving movement accuracy or durability with features like water resistance. These modifications provide watch enthusiasts the opportunity to create a unique timepiece that fits their personal preferences and enhances their watch-wearing experience.
Seiko modding is a fun and creative way to customize your watch. If you’re just starting, you’ll need basic tools and parts like dials, braces and hands to personalize your timepiece. Explore our shop forcompatible parts, and feel free to reach out for help identifying the right components or installing them. Our resources are here to make your modding journey easy and enjoyable!

A wristfriendly option
At Nomods, we design Seiko mod cases that are as wrist-friendly as they are stylish. The Petrichor case offers a balanced 37 mm diameter with a 45 mm lug-to-lug (51 mm including end link), delivering a comfortable fit without sacrificing wrist presence. Its slim profile makes it an ideal choice for modders looking to create custom Seiko mod watches that wear well all day.
Slimmest Seiko Mod?
Designed for serious Seiko mods, the Nomods Petrichor case uses a custom domed sapphire crystal that wraps around the Seiko movement’s hand stack. This innovation allows for a low-sitting bezel and minimal rehaut, eliminating the bulk and tall rehauts that many modders struggle with. The result is a slimmer, more balanced profile — perfect for building your dream Seiko mod watch.
