Ratchet

A ratchet is a toothed component used in the winding system of a mechanical watch, helping control the winding and release of mainspring power. It often works together with clicks, wheels, and springs to prevent unwanted reverse movement. Ratchets may be replaced when teeth are worn, broken, slipping, corroded, or causing problems with winding efficiency.
