The Audemars Piguet Royal Oak Perpetual Calendar John Mayer Limited Edition reference 26574BC.OO.1220BC.02 is a 41mm luxury timepiece crafted in 18k white gold. This collaboration features a unique Crystal Sky dial, which utilizes a new stamped scintillating pattern of irregular shapes to evoke the vastness of a starry night sky. The watch is powered by the self-winding Calibre 5134, a movement with a 40-hour power reserve that serves as a final tribute to this long-standing caliber. The case measures 9.5mm in thickness and maintains the iconic octagonal bezel and integrated bracelet, though it offers a limited water resistance of 20 meters.
The movement provides a comprehensive perpetual calendar complication, including indications for the day, date, month, and leap year, alongside an astronomical moon phase set against an aventurine background. Unique to this edition is the use of a light blue central hand for the week number display and a subtle modification to the date indicator, where the numeral 31 is printed in white and resized for better legibility. These complications are designed to remain accurate without manual adjustment until the year 2100, provided the watch is kept wound.
General reviews of the 26574BC highlight its status as a collector’s piece, often praising the innovative texture of the dial as a modern interpretation of vintage Tuscan designs. Enthusiasts appreciate the collaborative input from John Mayer, noting that the design remains refined and classic without overt celebrity branding. However, some critics point out that its white gold construction and high market value make it less of a traditional sports watch and more of a high-complication dress piece. Despite its exclusivity and the premium price point, the watch is widely regarded as a significant and aesthetically stunning conclusion to the era of the Calibre 5134.
