The latest entry in Blancpain’s Fifty Fathoms Tech BOC family — a series of hard-wearing dive watches with features for serious divers — the new Fifty Fathoms Tech BOC IV is a 45mm Grade 23 titanium beast with an integrated rubber strap, a Helium Escape Valve, a unidirectional bezel with a black ceramic timing insert, and a whopping 300m of water resistance. A black dial with luminescent indices and sword hands provides plenty of underwater visibility, while the automatic Calibre 1315A boasts a silicon balance spring, a five-day power reserve, and an 18K gold oscillating weight. $1,000 of each of the 1,000 pieces made will be allocated to the Blancpain x Sulubaaï Marine Research Center in the Philippines.
