The Audemars Piguet Royal Oak 56175SA is the mid-size expression of Gérald Genta’s design, pairing the collection’s unmistakable case architecture with two-tone construction and a factory diamond-set dial. This elegant timepiece features a 33mm stainless steel case measuring roughly 6mm thick, framed by a fixed 18k yellow gold octagonal bezel secured by eight white gold hexagonal screws and protected by scratch-resistant sapphire crystal. The captivating grey Tapisserie dial carries the waffle guilloché pattern that defines the Royal Oak, set with round brilliant-cut diamond hour markers and gold hands for a look that reads as both sporty and jeweled. Powered by a Swiss quartz movement, the 56175SA delivers low-maintenance accuracy with hours, minutes, and a date aperture at 3 o’clock. The integrated two-tone bracelet in stainless steel and 18k yellow gold completes the watch, built from the Royal Oak’s signature tapering links and secured by a hidden fold-over clasp with safety. Water-resistant to 30 meters, the Royal Oak 56175SA is one of the most wearable entries into the collection, slim enough to sit under a cuff and distinctive enough to be recognized across a room.
