Blancpain Fifty Fathoms Aqualung No Radiation 41MM Black Circa 1965

The Blancpain Fifty Fathoms Aqualung No Radiation is an icon of both horological and diving history, first produced in the mid-1960s. This 41mm stainless steel masterpiece, known for its distinctive “No Radiations” badge on the dial, was designed for professional and military divers requiring the utmost reliability and safety – free from radioactive luminescent paints previously common in the industry. Powered by a robust automatic movement, the reference became notable for its technical innovation, including high water resistance and a high-contrast, legible black dial. The Aqualung variant further underscores its ties to the pioneering period of underwater exploration, closely associated with Jacques Cousteau’s team. The unidirectional bezel and screw-down crown enhanced its functionality and safety at depth, solidifying its reputation among elite tool watches. Collectors value the original 1960s iterations for their rarity, impeccable design lineage, and pivotal role in the development of modern dive watches. The plain, monochromatic aesthetic and bold insignia ushered in a new era of clarity and safety standards which now permeate the industry. Today, this vintage Blancpain remains one of the most desirable and historically important dive watches ever manufactured, commanding the attention of connoisseurs and historians alike. Excellent condition.
