No affiliation with the Seiko brand

Modus Horlogerie is not affiliated with, sponsored by, or authorized by Seiko Group Corporation or any of its subsidiaries.

The concept of “Seiko Modding”

Watch modding involves personalizing a watch by replacing or combining certain elements (case, dial, hands, bezel, glass, strap, etc.) to create a unique piece, tailored to the taste of each enthusiast.

At Modus Horlogerie, we apply this concept through:

  • The use of Japanese automatic movements NH35, NH34 GMT, NH70 Skeleton, VK63 Chronograph , produced by Seiko Instruments Inc. (an independent industrial division of the Seiko group);
  • Hand-assembled in France , in our own workshop, by experienced watchmakers;
  • Rigorous quality control, including testing, adjustment and inspection of each watch before shipment.

Our commitment: quality, transparency and French craftsmanship

Each Modus watch is a personalized horological creation , designed with care, precision and passion.
We use only high-end components : sapphire crystal, 316L stainless steel, ceramic, Luminova luminous indices, adjustable straps and leather cases.

All our watches are:

  • Assembled and regulated in France 🇫🇷
  • 3-year warranty
  • Shipped from our French workshop with a certificate of authenticity
