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.

Each custom timepiece is hand built To ensure the highest possible standards, we have a lead time of 3 - 4 weeks from the date of order to delivery. This allows us to carry out the necessary quality control procedures and ensure that your watch is made to your satisfaction.

All orders placed through our website are subject to the given lead time even if the item is shown as "In stock".

Each watch is assembled by hand piece by piece in a completely handmade way by an expert with more than 11 years of experience.

We use Japanese movements, especially Seiko automatic movements, which are celebrated for their dependability, accuracy, and long-lasting performance.

Movements we use at Masterparts:

NH34-NH35-NH36-NH38 Automatic Movements

VK63 Mechanical Movement

Our watches are designed with a water resistance rating of 5 ATM, which makes them suitable for everyday use and able to withstand splashes or brief immersion in water.

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

To ensure the longevity and optimal performance of your watch, we recommend avoiding prolonged exposure to water.
