Blancpain Fifty Fathoms Bathyscaphe Chronographe Flyback 5200 3640 O52B
Details
The Blancpain Bathyscaphe Chronographe Flyback (Ref. 5200-3640-O52B) is a striking fusion of technical mastery and bold design. This version stands out with its sedna gold case, a luxurious and durable rose gold alloy that offers a rich, warm tone and excellent resistance to fading. At 43.6mm, the case is well-proportioned for contemporary tastes while retaining the sleek, utilitarian lines of the Bathyscaphe collection. The dial is a deep blue sunburst, complemented by gold-toned hands and markers coated with Super-LumiNova® for superior legibility in all conditions. The blue ceramic unidirectional bezel with Liquidmetal® markers provides precise dive timing and scratch resistance. A matching blue sail-canvas strap completes the look, enhancing both style and comfort while maintaining the tool-watch heritage. Inside, this model is powered by the Blancpain Caliber F385, a high-frequency (5 Hz) automatic movement equipped with a flyback chronograph, column wheel, and vertical clutch. These features ensure precise, reliable timing with seamless chronograph operation. The movement is visible through the sapphire crystal caseback, revealing meticulous finishing and a 50-hour power reserve. With 300 meters of water resistance, the 5200-3640-O52B blends luxury with true dive capability — a watch as technically impressive as it is visually compelling.
