Barrel

The barrel is the part of a mechanical watch movement that houses the mainspring, which stores and releases energy to power the watch. As the mainspring unwinds, the barrel transfers power through the gear train to keep the movement running. Barrels may be replaced during servicing when teeth, arbor holes, covers, or internal components show wear or damage.
