2023 Audemars Piguet 26574or Royal Oak Perpetual Calendar 41mm

The 2023 version of the 26574OR maintains the iconic 41mm 18k rose gold case but introduces subtle dial refinements, improved finishing, and enhanced legibility. It continues to house the ultra-thin Caliber 5134, known for its ability to display a full perpetual calendar in a sleek Royal Oak profile.

The perpetual calendar automatically adjusts for leap years, day, date, month, and moon phase — requiring no manual correction until the year 2100 (assuming it’s kept wound). It’s a showcase of mechanical mastery, especially given the movement’s slim 4.31mm profile.

While it is a high-complication luxury timepiece, the 26574OR is surprisingly wearable thanks to its lightweight profile and secure integrated bracelet. However, due to its precious metal construction and intricate movement, many collectors prefer to reserve it for special occasions.

The Caliber 5134 offers a 40-hour power reserve and runs at a frequency of 19,800 vph. While not a high-beat movement, it's engineered for long-term stability and reliable timekeeping, especially given the complexity of its calendar functions.

Yes, the 26574OR includes correctors recessed into the case sides for quick adjustments of the moon phase, date, and other calendar functions. However, it’s recommended to use the provided stylus and to avoid making adjustments during certain hours to prevent damaging the movement.
