Breguet Marine Alarme Musicale 5547

Breguet's Marine Alarme Musicale 5547, reference 5547BB/Y2/9ZU, is a GMT watch in a 40 mm white gold case. The case measures 13.1 mm thick, with lugs set 22 mm apart. A sapphire crystal covers the blue guilloché dial, and the screw-down crown protects the self-winding calibre 519F/1, which runs on a 45-hour power reserve. Beyond the central seconds and date, the movement drives an alarm function with its own 12-hour counter and a second time zone displayed at 9 o'clock. Hands and indices carry luminous treatment for reading in low light. A sapphire caseback exposes the movement's construction. The alligator leather strap closes with a white gold folding clasp, and the case is water resistant to 50 metres.
