Blancpain Fifty Fathoms Bathyscaphe

Blancpain created the Fifty Fathoms in 1953 at the request of French combat divers, and it is generally accepted as the first modern dive watch — predating every rival in the category. The Bathyscaphe is its more compact sibling, here in ceramic, a material that stays black and unmarked where steel would show every year of wear. The in-house calibre 1315 runs on three series-coupled barrels for a five-day reserve, with a silicon balance spring and a free-sprung balance adjusted by gold screws.
