Blancpain Fifty Fathoms 5015B-1130-52

This is the “Tribute to Fifty Fathoms,” a limited edition of 500 pieces released in 2010. Its significance lies in the faithful recreation of the historical “No Radiations” logo on its matte black dial. This symbol was used on civilian and military Fifty Fathoms in the mid-1960s to indicate that the watch’s luminous material was free from harmful radium. This was a critical safety feature at the time and is a key part of the model’s heritage. The tribute watch also features a vintage-style bezel, lacking the 15-minute graduation of the standard model. Powered by the modern Caliber 1315, this edition is a highly sought-after collector’s piece that celebrates a unique and important chapter in the history of dive watches.
