The Blancpain Bathyscaphe Chronographe Flyback (Ref. 5200-1210-NAGA) represents a modern evolution of the classic dive watch — combining Blancpain’s long-standing heritage in underwater exploration with state-of-the-art chronograph performance. With its Titanium construction and sleek monochromatic design, this model delivers high performance in a lightweight and stylish package. The watch features a 43.6mm satin-brushed Titanium case, which offers superior strength and corrosion resistance while remaining exceptionally light on the wrist. Its meteor grey sunburst dial adds visual depth and texture, complementing the neutral tone of the Titanium case. The dial includes three chronograph subdials and a date window between 4 and 5 o’clock, while Super-LumiNova® filled hands and markers ensure excellent legibility, day or night. A grey ceramic unidirectional bezel with Liquidmetal® markers surrounds the dial, providing a scratch-resistant and fade-proof surface ideal for dive timing. Paired with a grey NATO strap, the watch leans into a military-inspired aesthetic while offering secure comfort and durability, whether on land or at sea. Inside, the watch is powered by the Blancpain Caliber F385, a high-frequency automatic movement beating at 5 Hz (36,000 vph). This flyback chronograph movement allows for quick reset and restart of the chronograph with a single push — perfect for timing fast-paced activities. The movement features a column wheel, vertical clutch, and a 50-hour power reserve. Through the sapphire caseback, the expertly finished movement and engraved gold rotor are on full display. Rated for 300 meters of water resistance, the Bathyscaphe Chronographe Flyback 5200-1210-NAGA is built for deep-sea adventure while remaining refined enough for daily wear. Its Titanium build, muted tones, and practical chronograph make it a versatile and compelling choice for watch enthusiasts who appreciate modern tool-watch aesthetics paired with mechanical excellence.
