Blancpain Fifty Fathoms 5200-0153-B52A

The Blancpain Fifty Fathoms Bathyscaphe Flyback Chronograph “Ocean Commitment III” is a limited edition of 250 pieces released in 2018. Its significance is twofold: it supports Blancpain’s marine conservation initiatives (a donation is made for each watch sold), and it features a case made entirely of blue ceramic. This model combines a high-end, in-house flyback chronograph movement with the robust features of a professional dive watch. The vibrant blue color of the case, dial, and bezel is a defining aesthetic feature. It is powered by the Caliber F385, a high-frequency movement operating at 5Hz (36,000 vph), which allows for precision timing. The movement’s gold rotor is specially engraved with the “Ocean Commitment” logo, visible through the sapphire caseback. This reference is a testament to Blancpain’s technical prowess in material innovation and its dedication to ocean preservation.
