The staggeringly beautiful and technically unrivalled Classique Hora Mundi has continued to surprise us since its launch in 2011. Breguet’s in-house 5717 self-winding calibre brings to life the usual hour/minute functions plus a second time zone with instant time display, date display (at 12 o’ clock on the dial) and day/night indicator (at 3 o’ clock) for a previously selected city (at 6 o’ clock) without affecting the watch’s precision thanks to a stop seconds system. The aforementioned movement is housed in a 44mm rose gold or platinum case with delicately notched sides. In the centre of the dial lies a continent (the Americas, Europe, Africa or Asia and Oceania) whose surrounding ocean has been guilloche-engraved then coated in a translucent lacquer. The Roman numerals on the hour and minute track are positioned on a silver rim around the dial with two blue steel pomme-shaped hands. Price: 77,000 CHF (rose gold) – 92,000 CHF (platinum)
