The Blancpain Fifty Fathoms reference 5015-12B40-O52A is an iconic professional dive watch and a cornerstone of modern Swiss sports watchmaking. This certified pre-owned luxury watch is presented in new condition and offered as a full set with its original box and papers, making it a highly desirable example of Blancpain’s legendary diver.
The 45 mm case is crafted from satin-brushed titanium, combining exceptional strength with remarkable lightness and comfort on the wrist. Water-resistant to 300 metres, the case is fitted with Blancpain’s signature unidirectional rotating bezel, featuring a blue sapphire insert that is both highly scratch-resistant and luminous. The deep blue dial is clean, legible, and purpose-driven, with large applied hour markers and hands filled with Super-LumiNova for optimal underwater readability. A discreet date window is positioned at 4:30, preserving the dial’s balanced aesthetic. The watch is paired with a blue sail-canvas strap, reinforcing its robust yet refined character.
Powering this Fifty Fathoms is the in-house Blancpain calibre 1315, a high-performance automatic movement developed specifically for professional diving use. Equipped with three mainspring barrels, it delivers an impressive power reserve of approximately 120 hours. The movement is renowned for its reliability, precision, and durability, and is fully manufactured and assembled in Switzerland in accordance with Blancpain’s uncompromising standards.
This pre-owned Blancpain Fifty Fathoms Blue is a true tool watch with strong collector appeal, combining cutting-edge materials, iconic design, and outstanding mechanical performance. A benchmark pre-owned luxury dive watch for enthusiasts seeking a modern classic in exceptional condition.
