Breguet Marine 5517

The Breguet Marine 5517BR/G3/RZ0 is a 40 mm rose gold watch with a slate dial finished by hand-guilloché work. The case measures 11.5 mm thick, with lugs set at 22 mm apart. A sapphire crystal covers the dial, and a sapphire caseback on the reverse shows the self-winding calibre 777A, which runs with a 55-hour power reserve. Central seconds and a date aperture at 3 o'clock join the display, and the hands carry phosphorescent treatment for reading in low light. The screw-down crown, decorated with a wave motif, adds a further Marine touch. A rose gold bracelet with a folding clasp, also in rose gold, completes the piece. Breguet rates the case to 100 metres.
