This model is part of the Fifty Fathoms collection, which has a rich history dating back to its inception in 1953 as one of the first true diver’s watches. The Bathyscaphe version was introduced later in 1956, designed for everyday wear while maintaining its diving capabilities.
The Blancpain watch features a bracelet with each link meticulously crafted and secured using a patented cam-shaped pin system. This innovative design ensures exceptional sturdiness, preventing any twisting of the links, though it results in a chunkier feel. The bracelet’s black color seamlessly matches the case, creating a cohesive aesthetic, highlighted by a silver shimmer that changes with the light. For those seeking alternatives, the watch is also available with canvas or NATO-style straps.
Crafted from high-tech ceramic, the case boasts exceptional durability and scratch resistance, with a color that remains unfading. The black ceramic, with its brushed finish, gives off a subtle silver sheen in certain lighting. However, while visually striking, the ceramic does not reduce the watch’s considerable weight, making it a robust timepiece.
The moon phase complication is particularly notable, reflecting Blancpain’s dedication to combining watchmaking with astronomical precision. This feature allows the wearer to track the moon’s phases, adding a poetic element to the watch’s functionality.
