Blancpain 5010C Fifty Fathoms 70th Anniversary SS Black Dial LIMITED

The Blancpain Fifty Fathoms 70th Anniversary Act 1 Series III, reference 5010C-1130-NABA, was released in 2023 to mark 70 years of the Fifty Fathoms. This Series III version was reserved for the Americas and limited to 70 pieces as part of Blancpain's three-part anniversary series. Its 42.3 mm stainless steel case was created specifically for the anniversary model, landing between the size of early military Fifty Fathoms watches and current production references. The sunburst black dial, oversized luminous markers, and domed sapphire bezel insert draw directly from the design of the original 1953 Fifty Fathoms. Inside is Blancpain caliber 1315, an automatic movement with three barrels, a 120-hour power reserve, and a silicon balance spring for added resistance to magnetism. The 1315 is well regarded for its reliability and has become a mainstay of the modern Fifty Fathoms line. A sapphire display back shows the movement's special finishing and anniversary rotor. Paired with a black fabric NATO strap, this reference keeps the practical feel that defines the Fifty Fathoms while leaning more closely into the model's early history than most standard production versions. For buyers looking for a modern dive watch with real historical ties, the 5010C-1130-NABA is one of the more compelling limited Blancpain releases from the period.
