Breguet Marine 5517

Breguet's Marine 5517 (5517BR/Y2/5ZU) is a men's watch in an 18K rose gold case measuring 40 mm across. The case stands 11.5 mm thick, with lugs set at 22 mm, and the dial sits under a sapphire crystal. The self-winding movement is the calibre 777A, with 55 hours of power reserve, visible through a sapphire caseback. The blue guilloché dial carries luminous hands, a central seconds display and a date aperture at 3 o'clock. A screw-down crown, decorated with wave motifs, protects the movement, and the watch is fitted to a rubber strap with a rose gold folding clasp. Breguet rates the case to 100 metres.
