The Blancpain Bathyscaphe Chronographe Flyback Ocean Commitment (Ref. 5200-0310-NAGA) is a limited edition timepiece of just 250 pieces, created to honor and support Blancpain’s ongoing Ocean Commitment initiative. This model blends Blancpain’s dive watch heritage with a contemporary aesthetic and a mission-focused spirit, making it a standout choice for collectors and ocean advocates alike. The watch features a 43.6mm satin-brushed stainless steel case, which gives it a sturdy yet refined presence on the wrist. Its Sunburst Blue Dialreflects the depth and vibrancy of the sea, contrasted with three silvered chronograph subdials and a discreet date window positioned between 4 and 5 o’clock. The hands and indexes are filled with Super-LumiNova®, ensuring optimal legibility in any lighting condition, above or below the surface. A blue ceramic unidirectional rotating bezel with Liquidmetal® markers surrounds the dial, offering both scratch resistance and precision timing functionality for divers. The watch is fitted with a blue NATO strap, delivering lightweight comfort, security, and a sporty, mission-ready look in line with its conservation-driven purpose. Powering the watch is the Blancpain Caliber F385, an in-house, high-frequency (5 Hz) automatic flyback chronograph movement. It features a column wheel and vertical clutch, enabling smooth, precise chronograph operation and the ability to reset and restart the chronograph with a single push. The 50-hour power reserve and anti-magnetic properties ensure reliable performance in any environment. Through the sapphire caseback, the movement is visible alongside the exclusive Ocean Commitment rotor engraving, a signature detail reserved for this limited series. With 300 meters of water resistance, the Bathyscaphe Chronographe Flyback Ocean Commitment 5200-0310-NAGA is a professional-grade diver designed to make a difference — a watch that not only performs at the highest level, but also supports the preservation of the oceans it was made to explore.
