Blancpain Fifty Fathoms 50th Anniversary

About this reference

Released in 2003 to commemorate the model's 1953 debut, the Blancpain Fifty Fathoms 50th Anniversary (Ref. 2200-1130-71) was limited to 150 units across three series of 50 pieces each. This reference marked the transition of the Fifty Fathoms into the modern era, featuring a 40.3mm stainless steel case and a sapphire crystal bezel insert, which replaced the acrylic used in vintage iterations. It is powered by the Calibre 1151 automatic movement, providing a 100-hour power reserve. Collectors prioritize this reference for its specific dimensions, as it remains smaller than the subsequent 45mm standard production models. On the secondary market, these timepieces typically trade between $25,000 and $35,000 depending on the presence of the original dive light and specialized packaging. While the three series are technically identical, the case backs are individually numbered 1/50 for each specific market allocation.
