Audemars Piguet "Jumbo" Extra-Thin Openworked

Audemars Piguet's Royal Oak "Jumbo" Extra-Thin Openworked, reference 16204OR.OO.1240OR.03, has a 39 mm case in 18-carat pink gold. The case measures 8.1 mm thick and carries a sapphire crystal over the openworked dial. Inside is the self-winding Calibre 7124, purpose-built for this skeletonized construction, showing the hours and minutes through its slate grey mainplate and bridges. The finish contrasts against the pink gold case and bracelet. Skeletonization is the standout here, with no dial plate to obscure the movement's architecture. The bracelet is pink gold as well, fitted with an AP folding clasp. Water resistance sits at 50 metres.
