All the components of the movement must be able to move freely and work together optimally once the movement has been cased. The Perpetual rotor is designed to capture the energy generated by the wearer.

The system’s oscillating weight reacts to the slightest movement of the wrist and, as it rotates, winds the mainspring. The latter regularly releases the energy necessary for the mechanical movement to function. Thanks to this technology, through human movement, watches no longer need to be manually wound.
