Breguet Marine 5517

Breguet's Marine 5517BR/Y2/9ZU is a men's watch in 18K rose gold, measuring 40 mm across. The case stands 11.5 mm thick and carries a sapphire crystal over a blue guilloché dial. Inside is the self-winding calibre 777A, offering 55 hours of power reserve and visible through a sapphire display back. Central seconds and a date aperture at 3 o'clock keep the layout simple, and the hands carry phosphorescent treatment for legibility in low light. The screw-down crown is decorated with a wave motif in keeping with the Marine line. An alligator leather strap closes with a folding clasp in rose gold. That same crown, screwed down against the case, keeps water resistance to 100 metres.
