OUR CONCEPT

French know-how

Premium Seiko Mod Expertise

Our expertise has developed around Seiko Mods , the art of personalizing and enhancing watches using Seiko Instruments Inc. movements (NH35, NH38, NH70, NH34 GMT, VK63…).
At Modus Horlogerie, we go further: each Seiko Mod is checked, adjusted and then assembled in our workshop in France to offer a unique watch combining Japanese engineering and French craftsmanship .

We use only premium components: 316L stainless steel , sapphire crystal , custom dials, robust bracelets, and Seiko movements renowned for their reliability. Each watch undergoes rigorous quality control (accuracy, water resistance, alignment, and finishing).

Our ambition: to offer personalized watches of horological quality , accessible and durable.
This marriage between French craftsmanship and Japanese mechanical excellence makes Modus Horlogerie a benchmark for premium Seiko Mod watches .
