Fifty Fathoms – the first diver\u2019s watch<\/h5>\n

The story begins in 1952, when the French Ministry of Defence created a special combat unit known as \u2019The French Frogmen\u2019 under the supervision of Captain Maloubier as Lieutenant Riffaud. The officers set out to commission a watch for their special unit with the requirements to be actually dive and combat proof, with clear luminescent markers as well as a rotating bezel.<\/p>\n

\n
As diving computers weren\u2019t a thing of the 50\u2019s so knowledge of accurate time under water served a critical function in calculating decompression, the lockable bezel to show elapsed time was created. Visibility and legibility are key factors when submerged – so enter black dial and luminescent hands and indexes.<\/h5>\n<\/blockquote>\n

The \u2019Fifty Fathoms MIL-SPEC\u2019 watch was born in 1953 under the reign of, avid diver, Jean-Jaques Fiechter (then CEO of Blancpain). The name Fifty Fathoms originates from a British measurement unit of depth and the actual depth -divers could submerge safely with back-then-available equipment- 50 fathoms ~ 300ft ~ 91m. The watch got its shape in steel and rather large proportions (for the 50\u2019s!) of 42mm diameter coupled with long lugs and a screwed caseback. As the leading innovation behind making the actual water proof watch was the patented double O-ring seal in the crown. Also a automatic movement was chosen from the beginning to avoid unnecessary opening of (winding via) the crown.<\/p>\n

The modern Fifty Fathoms (pictured ref. 5015 1130 52A) houses the true to origin automatic caliber 1315, bi-directional winding with triple barrels (120h power reserve) and a free sprung balance – for better shock resistance. Over all a beautiful and highly finished movement in the robustness of a 45mm stainless steel diver\u2019s watch.<\/p>\n","protected":false},"excerpt":{"rendered":"
