“AIGUILLE D’OR” GRAND PRIX AWARD: AUDEMARS PIGUET ROYAL OAK SELFWINDING PERPETUAL CALENDAR ULTRA-THIN

The titanium watch, with a platinum bezel, is the world’s thinnest automatic perpetual calendar wristwatch. It is just 6.3 mm in height with a movement that is only 2.89 mm thin.

ICONIC WATCH PRIZE: AUDEMARS PIGUET ROYAL OAK ‘JUMBO’ EXTRA-THIN

This new take on the famous 39mm Royal Oak of 1972 draws elements from two much-loved past pieces. The pink gold toned ‘Petite Tapisserie’ from the 1992 Royal Oak’s 20th-anniversary edition and the 18K white gold case from 1992 is matched with an 18K white gold case and bracelet decorated by hand, with a refined alternation of polished and satin-brushed surfaces.

BEST CALENDAR AND ASTRONOMY WATCH: HERMÈS ARCEAU L’HEURE DE LA LUNE

This 43-mm grey gold watch simultaneously displays moon phases in both northern and southern hemispheres, with the help of two mobile counters that float over the meteorite or aventurine dial made to look like the cosmos with mother-of-pearl moons. The counters display time and date while maintaining horizontal orientation and revealing the moon discs.
