Frequently Asked Questions
What is a Seiko mod?
A Seiko Mod is a special watch hand-assembled from a Seiko automatic movement, combined with high-quality aftermarket components. Essentially, it's a customized version of a standard Seiko watch, created for those who want to tailor their timepiece to their specific style or needs.
The term “MOD” comes from “modification,” and these can range from minor aesthetic changes to more complex technical overhauls. Thanks to the wide availability of Seiko replacement parts, each Seiko Mod can be unique, combining Seiko reliability with an exclusive, personalized design.
Shipping times and costs
The estimated time from assembly to delivery is 10 to 20 business days, although this may vary depending on the destination country. Shipping is completely free, so you won't have to pay any additional charges when you receive your watch. We take care of the entire process, ensuring your order arrives safely and without complications.
Are they original?
We work with original Seiko movements, renowned for their reliability and durability. The other components are of the highest quality, but are not affiliated with the Seiko brand. We create unique watches; they are not replicas. AETERNUM has no relationship or affiliation with the Seiko brand.
All watches are handcrafted modifications, assembled by hand with Seiko-compatible movements and components. Each piece is unique, carefully customized, and made with high-quality materials.
