Fifty Fathoms

The Blancpain Fifty Fathoms, reference 5015-1130-71S, is one of the most iconic professional dive watches ever created, widely regarded as the original modern diving watch. First introduced in the 1950s, the Fifty Fathoms has become a benchmark in underwater watchmaking, combining uncompromising performance with refined Swiss craftsmanship. This certified pre-owned luxury watch is offered in new, never worn condition and is supplied with original papers only.

The watch is housed in a solid 45 mm stainless steel case, engineered to meet professional diving requirements while maintaining a refined presence on the wrist. The unidirectional black sapphire bezel offers exceptional scratch resistance and precise dive-time tracking. The black dial is clean, highly legible, and purpose-built, featuring large applied hour markers and hands filled with luminous material to ensure optimal visibility in low-light and underwater conditions. A discreet date window at 4:30 integrates smoothly into the dial design.

Powering the watch is the Blancpain in-house automatic Calibre 1315, a flagship movement renowned for its robustness and precision. Equipped with three mainspring barrels, this calibre delivers an exceptional approximately 120-hour (5-day) power reserve while maintaining stable chronometric performance. The movement is beautifully finished and visible through the sapphire crystal case back, reflecting Blancpain’s commitment to haute horlogerie even in a professional tool watch.

The watch is fitted with a stainless steel bracelet, offering durability, comfort, and excellent balance on the wrist. With a water resistance of 300 metres, the Fifty Fathoms fully lives up to its legendary status.

This pre-owned Blancpain Fifty Fathoms, reference 5015-1130-71S, represents a rare opportunity to acquire an unworn example of a true dive watch icon within the world of pre-owned luxury watches.
