Cannon Pinion

The cannon pinion is a movement component that carries the minute hand and allows the hands to be set through the winding stem. It plays an important role in transferring motion from the movement to the hands while maintaining the correct friction for hand-setting. Cannon pinions may be replaced when worn, loose, damaged, or causing slipping hands or poor time-setting function.
