Breguet Marine 5517

Breguet's Marine 5517 (5517TI/Y1/9ZU) is a men's 40 mm titanium watch with a blue sunburst dial. The case measures 11.5 mm thick, and the screw-down crown carries the wave decoration typical of the collection. Inside is the self-winding calibre 777A, offering 55 hours of power reserve and visible through a sapphire display back. A sapphire crystal also protects the dial, which shows central seconds, luminous hands and a date aperture at 3 o'clock. The alligator leather strap closes with a titanium folding clasp. Water resistance reaches 100 metres, a solid figure for a watch built around dress-watch proportions.
