Introducing the Blancpain Fifty Fathoms Tech Ref. 5029-12B30-94A, the next generation of professional dive watches—now a permanent cornerstone of Blancpain’s legendary Fifty Fathoms collection. Encased in lightweight Grade 23 titanium with a bold 45 mm profile, this watch is built for both extreme underwater environments and sophisticated urban lifestyles. Its “Absolute Black” dial absorbs 97 % of light for ultimate legibility, heightened by luminescent block markers and an orange seconds hand.

Powered by the house-made Caliber 1315A—with 5 days of power reserve, 4 Hz precision, and a silicon balance spring—this mechanical marvel features both a date display and a secured movement to resist shocks and mishandling. A sapphire exhibition caseback showcases its finely crafted architecture.

For the first time in Fifty Fathoms history, a tool-free interchangeable strap system brings versatility to the forefront. Swap between integrated rubber straps in black, white, or vibrant orange—each facilitating a different mood, from wetsuit to weekend. Add to that a 120-click ceramic bezel sculpted for gloved handling, a helium escape valve, and 300 metres of water resistance, and you have a true diver’s instrument reborn for everyday elegance.
