The Blancpain Bathyscaphe Chronographe Flyback Ocean Commitment (Ref. 5200-0240-O52A) is a rare and meaningful timepiece, produced in a limited edition of only 250 pieces worldwide. Created to support Blancpain’s ongoing Ocean Commitment initiative, this watch blends exceptional dive performance with environmental purpose. Crafted from satin-brushed grey ceramic, the 43.6mm case offers ultra-durable, lightweight wear and a refined matte finish. Its deep blue dial echoes the color of the sea and is enhanced by three chronograph subdials, a date window between 4 and 5 o’clock, and Super-LumiNova® hands and markers for high visibility. A blue ceramic unidirectional bezel with Liquidmetal® inserts completes the functional, sleek dive design. The watch is paired with a durable and comfortable blue sail-canvas strap, further reinforcing the marine-inspired aesthetic. Inside, the watch is powered by Blancpain’s in-house Caliber F385 — a high-frequency (5 Hz) flyback chronograph movement with a column wheel and vertical clutch for smooth, precise operation. The flyback function allows the chronograph to restart instantly with a single press. Through the sapphire crystal caseback, the beautifully finished movement and exclusive Ocean Commitment rotor engraving are visible. With 300 meters of water resistance, this timepiece is built for serious diving. But it also serves a higher purpose — a portion of each sale goes directly to supporting marine conservation projects. The Fifty Fathoms Bathyscaphe Chronographe Flyback Ocean Commitment 5200-0240-O52A is a rare opportunity to own a world-class dive watch that gives back to the very oceans it was designed to explore.
