Breguet Marine 5517

Breguet Marine 5517 (reference 5517BB/Y2/9ZU) is a men's watch in an 18K white gold case measuring 40 mm across. The case stands 11.5 mm thick and carries a sapphire crystal over a blue guilloché dial. Inside, the self-winding calibre 777A runs with a power reserve of 55 hours and can be viewed through the sapphire display back. The dial shows a central seconds hand and a date aperture at 3 o'clock, and the hands carry luminous treatment for low-light reading. A screw-down crown, decorated with wave motifs, protects the movement from the elements. The watch is fitted to an alligator leather strap secured by a white gold folding clasp. Water resistance reaches 100 metres.
