The Blancpain Fifty Fathoms Chronographe Flyback Ref. 5085FB-1140-71B is a distinguished timepiece that seamlessly blends the brand's rich diving heritage with contemporary horological innovation. Encased in polished stainless steel, its 45mm silhouette commands presence on the wrist while ensuring robust durability for underwater exploration. The deep Sunburst Blue Dial, paired with luminous Super-LumiNova® hands and indices, offers exceptional legibility under low light and evokes the mystique of the ocean depths. The unidirectional sapphire-topped bezel underscores its diver-centric functionality with precision and elegance. At the heart of the timepiece lies the Blancpain Caliber F185, a self-winding flyback chronograph movement developed and assembled in-house. This high-performance engine operates at 21,600 vibrations per hour and offers a 40-hour power reserve, seamlessly integrating advanced chronograph functionality with the convenience of a flyback mechanism—enabling immediate reset and restart with a single pusher. Comprising 308 meticulously finished components and 37 jewels, the movement is a testament to Blancpain’s horological heritage and mechanical sophistication. Engineered for the extremes, the watch boasts an impressive water resistance of 300 meters (30 bar), making it not only a symbol of refined taste but also a reliable companion for serious divers. The screw-down crown and secure chronograph pushers further reinforce its underwater readiness, while the anti-magnetic and shock-resistant construction ensures enduring accuracy in demanding environments. Every detail is purpose-driven yet luxurious, from the satin-brushed lugs to the engraved caseback that reveals Blancpain’s legacy of innovation in marine timekeeping. Completing the design is a stainless steel bracelet, tailored for comfort and resilience, fastened with a deployant clasp for added security. With its fusion of aesthetic purity and mechanical excellence, the Fifty Fathoms Chronographe Flyback is not merely a timepiece—it is a statement of craftsmanship, adventure, and enduring style.
