​Rarity and Historical Context
​Collectible Interest: A representative piece of the high-precision production of the Tavannes/Cyma factory in the early 20th century. The appeal lies in the pure calibre of the brand and the preservation of the dual numeration (12/24h) in cobalt blue on the dial, a typology highly sought after in the civilian market of the World War I era for its technical readability.
