Breguet Classique Hora Mundi 5719

Breguet's Classique Hora Mundi 5719, reference 5719PT/US/9ZV, is a GMT watch in a 46 mm platinum case. The case measures 15.1 mm thick, with lugs set at 23 mm apart, and the case band and lugs are set with baguette-cut diamonds and sapphires. A self-winding calibre 77F1 drives the watch, with 55 hours of power reserve, and a sapphire crystal covers the blue guilloché dial. The movement is visible through a sapphire caseback. Beyond the diamond setting, the watch switches instantly between two pre-selected time zones, and it also carries a date display and central seconds. The alligator leather strap closes with a platinum deployant clasp set with diamonds. Rated to 30 metres, the case favours dress wear over diving.
