The APEX collection is primarily aimed at true mechanical watch enthusiasts.
It represents our commitment to pushing the boundaries of our expertise by combining completely redesigned and skeletonized movements with premium and exotic materials such as forged carbon.
Every detail is designed to bring the mechanics to the forefront: open architecture, specific finishing, redesigned components, and chronometric performance individually tested in our workshop.
A more radical approach to N.A Timekeeping watchmaking, produced as a one-off piece.

WARNING — WATCH FOR THE DISCERNING ENTHUSIAST
The APEX collection is not recommended as a first mechanical watch.
Its fully skeletonized movement, complex architecture, and specific finishing make it a piece intended primarily for enthusiasts and collectors who already have some experience with mechanical watchmaking.
Like any highly complicated and largely skeletonized horological piece, it requires greater attention and care when used than a traditional mechanical watch.
If you are looking for your first automatic watch or a watch to wear daily without restrictions, we recommend exploring another N.A Timekeeping collection.
