The Blancpain Bathyscaphe Chronographe Flyback (Ref. 5200-0140-O52A) embodies the perfect union of advanced horology, technical dive specifications, and bold design. Its combination of deep ocean blue with high-tech ceramic materials creates a striking yet highly functional timepiece built for serious underwater performance and everyday sophistication. This model features a 43.6mm satin-brushed black ceramic case, offering exceptional scratch resistance, lightweight comfort, and a sleek matte finish. The standout feature is the rich Sunburst Blue Dial, which adds vivid depth and contrast. It’s equipped with three chronograph subdials, a date window between 4 and 5 o’clock, and Super-LumiNova® coated hands and markers to ensure legibility under any conditions. The dial is framed by a matching blue ceramic unidirectional bezel inlaid with Liquidmetal® markers for accurate dive timing and long-lasting clarity. The watch is fitted with a sail-canvas strap in blue, designed to be both rugged and comfortable — ready for open water or daily urban wear. Powering the watch is the Blancpain Caliber F385, a high-frequency (5 Hz) automatic chronograph movement featuring a flyback function, column wheel, and vertical clutch. This movement allows for smooth, instant restart of the chronograph with a single push and offers a 50-hour power reserve. A sapphire exhibition caseback reveals the beautifully finished movement, complete with a solid gold rotor engraved with the Blancpain logo. With 300 meters of water resistance, the Bathyscaphe Chronographe Flyback 5200-0140-O52A is designed for professional diving performance while maintaining the elegance and innovation expected from one of Switzerland’s most historic watchmakers. Its bold ceramic and blue accents make it a standout piece in the modern luxury dive watch category.
