Pinion

A pinion is a small toothed gear component used throughout a watch movement to transfer motion and power between wheels. Pinions are essential for the gear train, winding system, setting mechanism, and other functions. They may be replaced when teeth, pivots, leaves, or friction surfaces are worn, broken, corroded, or causing poor movement performance.
