Audemars Piguet Royal Oak “Jumbo” Extra Thin Openworked White Gold 39mm

The Audemars Piguet Royal Oak “Jumbo” Extra-Thin Openworked (ref. 16204BC.OO.1240BC.01) showcases the brand’s signature design in a bold, architectural execution. Crafted entirely in white gold, its 39mm case retains the iconic octagonal bezel with exposed screws, but shifts focus to the intricately skeletonised dial – an exhibition of mechanical transparency few can parallel.

Inside, the watch is powered by the self-winding calibre 7124, developed specifically for this openworked configuration. Despite the complexity on display, the movement remains impressively svelte, adhering to the “Extra-Thin” designation. The refined mechanics deliver a 57-hour power reserve and are fully visible through both the openworked dial and sapphire caseback. As with all Royal Oak models, the case and bracelet finishing – contrasting brushed and polished surfaces – is exemplary. Water resistance is rated at 50m.

Introduced in 2024, this white gold execution combines the enduring appeal of the original 1972 Royal Oak silhouette with one of the manufacture’s most daring contemporary movements. It’s a compelling bridge between Gerald Genta’s geometric legacy and modern technical prowess.
