Housed in a 41 mm 18-carat pink gold case, this Royal Oak presents a blue dial featuring the Grande Tapisserie pattern alongside blue counters, pink gold applied hour-markers, and Royal Oak hands with luminescent coating. A blue inner bezel frames the dial, while the 18-carat pink gold bracelet secures with an AP folding clasp. Water resistance is rated to 20 metres.
Powering the watch is a selfwinding calibre measuring 29 mm in diameter and 4.5 mm thick, oscillating at 2.75 Hz (19,800 vph) and offering a 40-hour power reserve. Its 374 components and 38 jewels support a perpetual calendar complication that simultaneously displays week indication, day, date, astronomical moon, month, and leap year alongside hours and minutes.
The perpetual calendar mechanism requires no manual correction at month-end, autonomously tracking the irregularities of the Gregorian calendar. Reference 26574OR.OO.1220OR.03 represents a compelling convergence of horological complexity and the Royal Oak's enduring architectural design language.
