Breguet Marine 5517

Breguet's Marine 5517 (5517BB/Y2/5ZU) is a men's watch with a white gold case measuring 40 mm across. The case stands 11.5 mm thick, and the screwed crown carries a wave-pattern decoration typical of the collection. A sapphire crystal covers the blue guilloché dial, and a sapphire caseback shows the self-winding calibre 777A, which runs with 55 hours of power reserve. The dial combines central seconds and a date aperture at 3 o'clock, with luminous hands for low-light legibility. A rubber strap closes with a white gold folding clasp. The screw-down crown backs up the case's water resistance, rated to 100 metres.
