Fifty Fathoms, 5015-12B40-52A

First introduced in 1953 under Blancpain’s then CEO Jean-Jacques Fiechter, himself a diver, the Fifty Fathoms is widely regarded as the original modern dive watch. It set the blueprint: exceptional legibility, a secure rotating bezel, and true underwater reliability. While others followed, Blancpain was already there, defining the category. Today, it remains something of a connoisseur’s choice. Less pervasive and more considered, it's the kind of dive watch those in the know tend to gravitate towards. This reference, 5015-12B40-52A, brings that legacy into a more contemporary space. The lightweight titanium case is paired with a deep blue dial and matching sapphire bezel, giving it a clean, technical edge while staying true to the original design language. Inside, the in-house Calibre 1315 delivers a five-day power reserve, backed by a robust 300 metres of water resistance, proof that the Fifty Fathoms is still every bit the capable tool watch it was designed to be. Our 2023 Fifty Fathoms is offered as a full set in excellent condition, with only light signs of wear and remains unpolished. Viewings are encouraged at our Knightsbridge showroom
