Breguet Marine 9518

Breguet Marine 9518 (reference 9518ST/5W/584) comes in a 33.8 mm steel case, set with diamonds. The case measures 9.9 mm thick, with lugs spaced 18.5 mm apart. A self-winding calibre 591 A drives the watch, built with 187 components and a flat silicon balance spring. It offers 38 hours of power reserve, visible through a sapphire display back. The mother-of-pearl dial carries central seconds and a date, with luminous hands for legibility in low light. A sapphire crystal protects the dial. A folding clasp in steel closes the rubber strap. The case is rated to 50 metres, ample for everyday wear rather than diving.
