Breguet Marine 5517

The Breguet Marine 5517 (ref. 5517TI/Y1/TZ0) is a 40 mm titanium case with a blue sunburst dial. The case measures 11.5 mm thick, with lugs set 22 mm apart, and the screw-down crown carries the wave decoration typical of the collection. Self-winding calibre 777A drives the watch, with a power reserve of 55 hours, and the sapphire crystal caseback exposes the movement and its rudder-shaped oscillating weight. A date aperture sits alongside central seconds, and the hands carry luminous treatment for low light. The titanium bracelet closes with a titanium folding clasp. Breguet rates the case to 100 metres of water resistance.
