Blancpain Bathyscaphe Chronographe Flyback

Blancpain's Bathyscaphe Chronographe Flyback, reference 5200 0153 B52A, is a chronograph with a 43.6 mm ceramic case. The case measures 15.25 mm thick, and the unidirectional rotating bezel sits above a sunburst green dial under a sapphire crystal. Inside is the self-winding calibre F385, giving 50 hours of power reserve. The flyback chronograph resets and restarts in one motion, and small seconds and a date complete the layout. Lug width runs 23 mm, wide enough for the sail-canvas strap fitted with a pin buckle. The case is rated to 300 metres, a figure that keeps this chronograph genuinely dive-capable rather than merely styled for it.
