Présentation du mouvement automatique squelette d'une montre seiko mod

Hand assembled

Each watch is assembled in our workshop located in France . We use Seiko automatic movements as a base, renowned for their robustness and reliability.
All operations are carried out manually : aligning the hands, installing the dial, inserting the movement into the case, lubricating the movement and the multiple seals, and testing the oscillating weight. Each Seiko Mod is rigorously checked after assembly to ensure its proper functioning , the centering of the hands and the water resistance of the case. This process guarantees stable daily precision and a watch ready to last .
