The Blancpain Bathyscaphe Chronographe Flyback (Ref. 5200-1110-B52A) merges high-performance functionality with understated elegance in a rugged, modern design. This chronograph is a standout piece within the Fifty Fathoms family, combining Blancpain’s legendary dive-watch heritage with a technically advanced flyback chronograph movement — purpose-built for precision, endurance, and versatility in demanding environments. The watch features a 43.6mm satin-brushed stainless steel case, offering a bold yet wearable presence on the wrist. Its meteor grey sunburst dial is both refined and legible, displaying subdials for chronograph functions while maintaining a balanced, clean layout. The hands and applied markers are coated with Super-LumiNova®, ensuring visibility in all lighting conditions — whether you're in the depths of the ocean or the middle of a night flight. At the heart of the watch is the exceptional Blancpain Caliber F385, a high-frequency flyback chronograph movement beating at 36,000 vibrations per hour (5 Hz). The flyback function allows the chronograph to be reset and restarted instantly with a single press — ideal for precise timing on the go. The movement is fully visible through the sapphire exhibition caseback, showcasing its column wheel, vertical clutch, and finely decorated rotor. It boasts a 50-hour power reserve and is engineered for durability, anti-magnetism, and performance under pressure. A unidirectional satin-brushed steel bezel with a grey ceramic insert and Liquidmetal® hour markers reinforces the watch’s idenTity as a true dive instrument, while its 300-meter water resistance guarantees professional-grade performance underwater. The piece is paired with a black sail-canvas strap, offering rugged style and a comfortable, secure fit on the wrist. The Bathyscaphe Chronographe Flyback 5200-1110-B52A stands at the crossroads of vintage dive-watch legacy and cutting-edge horology — a sophisticated tool for explorers, sportsmen, and watch aficionados who demand precision and authenticity in equal measure.
