What is a Seiko Mod ?

A Seiko Mod watch is a customized version of a standard Seiko watch.

The term "MOD" comes from "modification". These modifications are generally made for those who wish to personalize their watch according to their specific tastes or needs. Modifications can vary considerably, from minor aesthetic changes to more complex technical revisions.

What makes Seiko watches particularly amenable to modification is the wide availability of spare parts. This abundance of components enables a wide range of customization, making each Seiko MOD watch unique.

However, they are not intended for swimming or taking baths.
