Blancpain's founding in 1735 makes it one of the oldest watchmaking names in existence, though the modern brand was revived by Jean-Claude Biver in 1983 with a powerful statement: Blancpain would never make a quartz watch. The Fifty Fathoms (1953) is the original modern dive watch — predating the Rolex Submariner — commissioned by Captain Robert Maloubier for French Navy combat swimmers. The Villeret line represents classical haute horology with some of the most refined complications available. Blancpain movements feature meticulous hand-decoration visible through display casebacks. The brand's annual production remains deliberately limited, and its connection to ocean conservation through the Blancpain Ocean Commitment adds purpose to prestige.
