Blancpain Fifty Fathoms 5200-0240-NAOA

The Blancpain Fifty Fathoms Bathyscaphe Flyback Chronograph Ocean Commitment II is a 250-piece limited edition from 2016. Its significance lies in its support of marine conservation and its pioneering use of an all-blue ceramic case. The 43.6mm case is lightweight, scratch-resistant, and features a unique satin-brushed finish. The watch is a professional diving instrument with 300m water resistance and a high-end flyback chronograph function. It is powered by the Caliber F385, a high-frequency (5Hz) movement allowing for 1/10th of a second timing. A special 18k gold rotor with the “Ocean Commitment” engraving is visible through the caseback. This reference is a collector’s piece that combines advanced material technology, horological complexity, and a philanthropic mission.
