FAQ


What is Seiko Mod Shop?

We are NOT authorized Seiko dealer! We are individual workshop specialized in watch modding and prototyping to manufacturing!

Seiko Mod Shop is one of the world's leading service companies for the customization and personalization of Seiko watches. An experienced team of specialists transforms from the bracelet to the dial - according to individual customer requirements. All our designs have Seiko automatic or quartz movements inside. Also upon request, we can discuss any other modifications and an individual movement.

Modification process?

The manufacturing process of a Seiko Mods is complex and requires great attention to detail. First, the basic watch to be modified must be chosen, along with the parts that will be used to customize the design. Modifications can include changes to dials, bezels, bracelets, crowns, indexes, cases and even movements to make in unique. All depends from customer choice.

The only thing that will always be in our watches is Seiko movements.
