Arogno 152 barrel drum with cover

Arogno

Arogno is a historic watch name associated with Swiss watchmaking, particularly vintage mechanical wristwatches from the mid-20th century. The brand is known for classic, understated designs that reflect the practical and elegant style of traditional Swiss watches of its era. Arogno watches are appreciated by collectors and enthusiasts for their vintage character, mechanical simplicity, and connection to the broader heritage of Swiss watch production.

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.
