2023 marks the 70th anniversary of Blancpain's Fifty-Fathoms, and we're taking a closer look at the Fifty-Fathoms 'Aqua-Lung'. Shortly after its introduction in 1953, the Fifty-Fathoms caught the eye of oceanographer Captain Jacques Cousteau, who became a major supporter of the watch for diving. Cousteau, along with Emile Gagnan, co-developed a diving regulator they called the ‘Aqualung’. As that technology became a success, they began using the name Aqua-Lung for their retail operations, and they elected to sell the watch in their stores with a co-branded dial. The present watch is in near time-capsule condition with a flawless gloss radium dial, and perfectly puffy and cream-colored indices and Arabic numerals. It will be offered in ‘Important Watches’ at #SothebysNewYork on 7 December—more details to follow. #SothebysWatches #Blancpain
