Blancpain Fifty Fathoms 5015-12B40-O52A

The Blancpain Fifty Fathoms Automatique 5015-12B40-O52A is a lightweight, modern interpretation of the iconic dive watch, rendered in Grade 23 titanium. Its historical context is rooted in the original 1953 Fifty Fathoms, one of the first true purpose-built dive watches. This contemporary version maintains the classic 45mm case diameter but offers significantly reduced weight and increased corrosion resistance due to its titanium construction. A key feature is its striking anthracite sunburst dial, which provides excellent contrast for the large, luminous hands and hour markers, ensuring legibility. The signature unidirectional sapphire bezel remains a durable and functional hallmark. The watch is powered by the robust in-house Caliber 1315, providing an exceptional 120-hour power reserve. This reference is typically paired with a black NATO strap, emphasizing its sporty, utilitarian identity.
