The Audemars Piguet Royal Oak Perpetual Calendar reference 26614OR.ZZ.1220OR.01 is a highly exclusive luxury timepiece limited to just 20 pieces. This model is defined by its 41mm case and integrated bracelet, both meticulously crafted from 18k rose gold. A standout feature of this particular reference is its bezel, which is set with 32 baguette-cut diamonds, providing a more refined and opulent aesthetic compared to standard brilliant-cut variations. The black Grande Tapisserie dial offers a sophisticated backdrop for the rose gold applied hour-markers and Royal Oak hands, all treated with a luminescent coating for enhanced legibility.
Mechanically, the watch is powered by the ultra-thin self-winding Calibre 5134, which is visible through a sapphire crystal caseback. The perpetual calendar complication is remarkably comprehensive, tracking the day, date, month, and leap year, as well as providing a week indicator on the outer chapter ring and an astronomical moon phase display. This movement is designed to automatically account for months of different lengths and leap years, requiring no manual adjustment until the year 2100. Despite its technical complexity, the watch maintains a relatively slim profile with a case height of 9.5mm, though its water resistance is limited to 20 meters, making it suitable only for light splashes.
General reviews of this reference emphasize its status as a “power move” or “flex piece,” noting that the combination of full rose gold and a diamond-set bezel creates a bold and unmistakable wrist presence. Collectors often praise the legibility of the black dial against the rose gold sub-dials and the exceptional finishing of the integrated bracelet, which is frequently described as a work of art that conforms comfortably to the wrist. While the limited production makes it a highly sought-after investment piece, common points of caution include the susceptibility of rose gold to scratches and the significant maintenance costs associated with servicing such a complex mechanical movement.
