Breguet Classique Hora Mundi 5719

Breguet's Classique Hora Mundi 5719, reference 5719PT/EU/9ZV, is a GMT watch in a 46 mm platinum case. The case measures 15.1 mm thick and carries lugs 23 mm wide. Set with diamonds, the case band and lugs also carry baguette-cut sapphires alongside further stones on the dial and clasp. The self-winding calibre 77F1 drives the watch with 55 hours of power reserve and sits under a sapphire crystal, with a sapphire case back on view from behind. The blue guilloché dial shows a date and central seconds alongside the second time zone display, which switches instantly between two pre-selected zones. An alligator leather strap closes with a platinum folding clasp. Water resistance is a modest 30 metres, in keeping with the dress proportions of the piece.
