A unique watch, for an end of the year like no other.
Personalization has never been more popular, and watchmaking is no exception. As 2025 draws to a close, Seiko Mods— custom watches made with genuine Seiko movements—are emerging as the perfect gift for watch enthusiasts and style lovers.
At Modus Horlogerie , we hand-assemble each model in our French workshop, combining Japanese mechanics and artisanal expertise . The result: a reliable, elegant, and above all, unique watch.
What is a Seiko Mod?
A Seiko Mod (for modified Seiko ) is a watch that is fully customized from an original Seiko movement , such as the famous NH35, NH38 or VK63 .
Around this movement, each component is carefully chosen:
-
Case (steel, rose gold, black PVD…)
-
Dial and hands
-
Bezel, insert, glass, case back
-
Bracelet (steel, rubber, leather…)
This concept allows you to create a watch inspired by iconic designs (Nautilus, Submariner, Royal Oak, Daytona, etc.), while taking advantage of the reliability of the Seiko movement and the freedom of personalization.
🇫🇷 The excellence of French assembly
