Blancpain Fifty Fathoms Bathyscaphe Steel — Meteor Grey Dial, Ceramic Bezel, Steel Bracelet | Ref. 5000-1110-70B

In 1953, Blancpain — the world's oldest watch brand, founded in 1735 — collaborated with French naval officer Bob Maloubier to create the Fifty Fathoms: the first purpose-built modern diving watch. That pioneering instrument established the DNA that every Fifty Fathoms descendant carries to this day. The Bathyscaphe, introduced as a sportier, more contemporary interpretation of that legend, retains every technical virtue of its ancestor while adding a new dimension of wearability — a watch equally at home descending to 30 bar of pressure as it is navigating a metropolitan dinner.

Calibre 1315, Blancpain's in-house automatic movement and the technical backbone of the Fifty Fathoms Bathyscaphe, delivers approximately 120 hours of power reserve through a triple-barrel architecture — a remarkable five days of autonomy that reflects the demands of extended maritime missions. The 43 mm satin-brushed steel case, 13.40 mm thick, is sealed to 30 bar water resistance and features a sapphire caseback that reveals the movement's architecture. The unidirectional bezel — a non-negotiable safety feature for divers — is crafted with a ceramic insert and Liquidmetal hour-markers that resist scratching and fading across decades of use.

The meteor grey dial is a masterwork of legibility: bold applied indices, high-contrast luminous coatings, and a symmetrical layout ensure instant readability at depth, in darkness, or under pressure. The satin-brushed steel bracelet with its folding buckle provides robust security and an integrated aesthetic that underscores the watch's purpose-built character. Priced at CHF 10,480, this Bathyscaphe occupies a compelling position in the sports-watch market — technically formidable, historically unimpeachable, and aesthetically refined in the manner that only Blancpain can achieve.
