Breguet Classique Hora Mundi 5719

Breguet's Classique Hora Mundi 5719PT/AS/9ZV is a GMT watch with a platinum case measuring 46 mm across. The case stands 15.1 mm thick, and the case band and lugs carry baguette-cut diamonds and sapphires set with diamonds throughout. Inside is the self-winding calibre 77F1, giving 55 hours of power reserve, visible through a sapphire caseback. The blue guilloché dial sits under a sapphire crystal and shows a date and central seconds alongside the watch's signature complication: two pre-selected time zones that switch instantly at the touch of a button. An alligator leather strap closes with a platinum folding clasp, itself set with diamonds. Water resistance is modest at 30 metres, reflecting the piece's dress rather than sport orientation.
