When the crown is turned, the winding pinion transfers this motion to the mainspring, storing energy to power the watch. Made from durable materials, this pinion ensures smooth and reliable operation of the winding and time-setting functions. It is a critical replacement part for servicing or repairing movements, helping to restore the watch's functionality and performance.

It is a key replacement part for servicing or repairing NH35 and NH36 movements, helping to restore the watch's functionality and precision.
