Peseux 280 barrel drum with cover

Peseux

Peseux is a historic Swiss movement manufacturer known for producing high-quality hand-wound calibres. The company’s movements were used by many watch brands and are especially appreciated for their slim construction and reliable performance. Peseux calibres are valued by watchmakers and collectors for their elegant engineering, serviceability, and important place in Swiss movement history.

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.
