The Blancpain Bathyscaphe Chronographe Flyback (Ref. 5200-0140-NAOA) merges contemporary materials, bold design, and expert mechanical engineering to deliver a luxury dive watch with true tool-watch capabilities. With its blue-on-black colorway and rugged NATO strap, it offers a compelling mix of sportiness, precision, and sophistication. The watch features a 43.6mm satin-brushed black ceramic case, prized for its scratch resistance, light weight, and stealthy matte finish. Its Sunburst Blue Dial provides striking contrast, enhanced by three chronograph subdials and a date aperture between 4 and 5 o’clock. Super-LumiNova® coated hands and markers ensure outstanding readability in all lighting environments — from deep underwater to low-light conditions on land. Framing the dial is a blue ceramic unidirectional rotating bezel, marked with Liquidmetal® inserts for optimal durability and legibility. The blue NATO strap adds a tactical edge to the overall design, offering a lightweight, breathable, and secure fit ideal for diving or casual daily wear. Inside, the watch houses the in-house Blancpain Caliber F385 — a high-frequency (5 Hz) automatic flyback chronograph movement that features a column wheel and vertical clutch for smooth operation. The flyback function allows the chronograph to be reset and restarted instantly with one push. The beautifully finished movement is visible through the sapphire crystal caseback, revealing a solid gold rotor and fine decorative details. It provides a robust 50-hour power reserve. With 300 meters of water resistance, the Bathyscaphe Chronographe Flyback 5200-0140-NAOA is engineered for serious diving while maintaining Blancpain’s timeless elegance and mechanical excellence. Its distinctive blue tones and high-tech materials make it a standout piece in any modern watch collection.
