Blancpain Fifty Fathoms Chronographe Flyback

Blancpain's Fifty Fathoms Chronographe Flyback, reference 5085F 1130 52A, is a steel chronograph with a 45 mm case. The case measures 15.5 mm thick, and the lugs take a 23 mm strap. A sapphire crystal covers the black dial. The self-winding calibre F185 drives the watch and stores 40 hours of power reserve. Flyback function sits alongside a chronograph, small seconds and date, all useful for a tool watch built around timing functions. Blancpain fits it to a sail-canvas strap with a pin buckle. The screw-down build holds the case to a 300 metre water resistance rating.
