This Audemars Piguet Royal Oak transformed watchmaking when Gérald Genta designed it in 1972, establishing the luxury steel sports watch as a category and becoming Audemars Piguet's defining icon. Reference 67650ST represents the mid-size 33mm Quartz execution — historically positioned within the ladies' catalog but increasingly worn unisex as smaller proportions return to favor among collectors. Notably worn by Serena Williams, the model carries the same architectural vocabulary as its larger counterparts: the octagonal bezel with eight exposed hexagonal screws, integrated bracelet, and signature "Grande Tapisserie" dial. Quartz movement allows a remarkably slim 7mm profile while maintaining the precision standards expected of the manufacture, making this a versatile and refined point of entry into the Royal Oak collection.

The 33mm case in stainless steel measures just 7mm thick, framed by the signature octagonal bezel secured by eight hexagonal screws, with a screw-down crown and glareproof sapphire crystal. The black "Grande Tapisserie" dial carries white gold applied hour markers and Royal Oak hands with luminescent coating, and a date aperture at three. The precision quartz Caliber 2713 powers the hours, minutes, and date, completed by an integrated stainless steel Royal Oak bracelet with AP folding clasp.
