Blancpain Bathyscaphe Chronographe Flyback

Blancpain's Bathyscaphe Chronographe Flyback, reference 5200 3640 O52A, is a chronograph in a 43 mm red gold case. The case measures 14.9 mm thick, with lugs set at 23 mm apart. A sapphire crystal covers the sunburst blue dial, and a unidirectional rotating bezel surrounds it. The self-winding calibre F385 drives the watch, with 50 hours of power reserve on offer. Flyback chronograph function, small seconds and a date window round out the display. Blancpain fits the watch to a sail-canvas strap secured with a pin buckle. The case holds a 300 metre water resistance rating, suited to the dive-watch pedigree of the Fifty Fathoms line.
