Breguet Marine 5517

The Breguet Marine 5517TI/G2/5ZU is a men's watch with a titanium case measuring 40 mm across. The case stands 11.5 mm thick, with lugs set 22 mm apart, and the slate dial sits under a sapphire crystal. The self-winding calibre 777A drives the watch and offers 55 hours of power reserve, with a display back that shows the oscillating weight through sapphire. Central seconds and a date aperture at 3 o'clock round out the display, and the hands carry luminous treatment for visibility. A screw-down crown, decorated with wave motifs, secures the case, and the watch is fitted to a rubber strap with a titanium folding clasp. The case carries a 100 metre water resistance rating.
