Housed in a 37mm 18-carat white gold case, this Royal Oak carries the hallmark octagonal bezel and a purple dial dressed with the "Grande Tapisserie" pattern. White gold applied hour-markers and Royal Oak hands with luminescent coating complete the dial, while water resistance to 50 metres speaks to the model's enduring versatility.
The watch is fitted with an 18-carat white gold bracelet secured by an AP folding clasp, and comes accompanied by an additional purple rubber strap. The selfwinding calibre — 26.2mm in diameter and 3.9mm thick — comprises 188 parts and 29 jewels, oscillates at 4 Hz (28,800 vph), and delivers a power reserve of approximately 60 hours.
Functions include hours, minutes, centre seconds, and date, presenting the essential Royal Oak toolkit within a refined white gold and purple aesthetic that sets reference 15551BC.ZZ.1356BC.02 apart from the broader collection.
