FAQ's

What is a Seiko Mod?

A Seiko Mod is a special watch hand-assembled from a prestigious Seiko automatic movement, combined with high-quality aftermarket parts, usually made of 316L stainless steel.

Have you ever dreamed of acquiring your ideal timepiece?
The purpose of Seiko mods is to bring the designs of luxury watches to a wider audience without resorting to counterfeit products, and by always using the best materials, such as sapphire crystal or ceramic bezels.

How can I adjust the size?

We include (for free) a complimentary tool kit with every order to help you adjust the strap properly and easily.

Are they original?

We use genuine Seiko movements to create unique watches inspired by top designs.

Our timepieces are not replicas and we are not affiliated with the Seiko brand in any way.
