Blancpain Fifty Fathoms

The Blancpain Fifty Fathoms (Reference 5015-12B40-O52A) is the legendary and pioneering professional dive watch, widely regarded as the originator of the modern dive watch category, offering uncompromising performance and classic design. Crafted from lightweight titanium with a 45 mm case, it presents a highly legible and functional aesthetic with its iconic blue dial, luminous markers, and a unidirectional rotating bezel with a sapphire insert. Powered by the in-house automatic Caliber 1315, it offers an exceptional 5-day (120-hour) power reserve from its three mainspring barrels. The blue textile strap with titanium buckle and 300-meter water resistance underscore its serious aquatic capabilities, making it the definitive tool watch for the serious diver and collector of horological history. The watch is in very good condition with only minor, intangible signs of wear, and includes its original box and papers.
