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!
