A category-defining dive watch

Launched in 1953, the Fifty Fathoms is the first true diver's watch. Created by a diver to meet the needs of underwater exploration, it was chosen by diving pioneers and combat diver corps around the world as a professional timekeeping instrument. With its water resistance, robust doubled-sealed crown, self-winding movement, contrasting dark dial with luminescent indications, lockable rotating bezel and anti-magnetic protection, the Fifty Fathoms has become an indispensable instrument for divers on their underwater missions. These key signature elements that established the Fifty Fathoms as the archetypal diver's watch continue to define the identity of such timepieces for the entire watch industry.

New for 2025, this Fifty Fathoms completes the trio of Blancpain's expanded size offerings for this iconic diver, with a newly engineered 38mm choice, complementing the 42 and 45mm references in the collection.
