The Audemars Piguet Royal Oak “Jumbo” Extra-Thin Openworked Ref. 16204BC.OO.1240BC.01 pairs the iconic Royal Oak design with exceptional openworked craftsmanship. Its 39mm case and integrated bracelet are crafted entirely from 18k white gold, creating a cool, understated frame for the contrasting dark gray skeletonized movement. Visible from both the front and exhibition caseback, the self-winding Caliber 7124 reveals the intricate architecture and hand-finishing behind the watch. White-gold hour markers and Royal Oak hands with luminescent coating provide clarity while preserving the open, technical character of the dial. At only 8.1mm thick, this “Jumbo” maintains the elegant proportions collectors associate with the original Royal Oak while delivering the presence of a full precious-metal construction. The movement offers hours and minutes, a frequency of 28,800 vibrations per hour, and approximately 57 hours of power reserve.
