Blancpain Fifty Fathoms 5015C-1130-52B

This reference, part of the 2007 Fifty Fathoms relaunch, is a special tribute to the historic “Aqua Lung” versions of the 1950s. Its significance lies in its historically faithful details. The matte black dial features the “Aqua Lung” logo, referencing the partnership with Jacques Cousteau’s diving equipment company which distributed the original watches. It also includes a “No Radiations” symbol, a nod to vintage models that used this to indicate the absence of radioactive radium lume. The sapphire bezel is also unique, featuring markings at every five-minute interval but omitting the fully graduated scale for the first 15 minutes, mirroring the design of some of the earliest Fifty Fathoms. Powered by the modern caliber 1315 with a 120-hour power reserve, this watch is a direct homage to a key part of the Fifty Fathoms’ commercial history, making it highly collectible.
