Audemars Piguet Royal Oak “Jumbo” Extra-Thin – 39mm Yellow Gold with Full Yellow Sapphire Pavé

This Audemars Piguet Royal Oak “Jumbo” Extra-Thin model (Ref. 16202BA.HH.1241BA.01) represents the pinnacle of haute joaillerie meets horological heritage. The 39mm case, octagonal bezel, integrated bracelet, and even the dial are entirely encrusted with 1,528 brilliant-cut yellow sapphires totaling approximately 10.4 carats — creating a dazzling, sunburst-like effect that catches light from every angle. Despite its lavish gem-setting, the watch retains its signature slim profile at just 8.1mm thick, thanks to the in-house Calibre 7121 automatic movement, which offers a 52-hour power reserve and is visible through the sapphire crystal caseback. The dial features applied hour markers and Royal Oak hands, all finished in matching yellow gold with luminescent fill for legibility. Water-resistant to 20 meters and secured with an AP-branded folding clasp, this masterpiece is not merely a timekeeper but a wearable sculpture — ideal for collectors seeking rarity, craftsmanship, and bold elegance.
