Wheel

Wheels are essential rotating components in a watch movement, used to transfer power, motion, and timing between different mechanisms. They appear throughout the gear train, winding system, setting system, calendar, chronograph, and automatic winding works. Wheels may be replaced when teeth, pivots, spokes, or friction surfaces are worn, bent, broken, corroded, or causing poor performance.
