Blancpain Fifty Fathoms Chronographe Flyback

Blancpain's Fifty Fathoms Chronographe Flyback, reference 5085F 3630 52A, has a 45 mm case in red gold. The case measures 15.5 mm thick, with a lug width of 23 mm. A sapphire crystal covers the black dial. This is a chronograph built around the self-winding calibre F185, which runs with a 40 hour power reserve.

Blancpain rates the case to 300 metres.
