This timepiece seamlessly integrates timeless design with advanced complications, embodying the pinnacle of Swiss watchmaking excellence.

Overview

Introduced as an evolution of its predecessors, this Royal Oak Perpetual Calendar features a harmonious blend of aesthetic allure and mechanical prowess. Its 41mm 18-carat pink gold case houses a richly detailed blue dial adorned with the iconic "Grande Tapisserie" pattern, offering both visual depth and clarity. The watch's perpetual calendar complication accurately displays the date, day, month, week, and moon phases, requiring no manual adjustment until the year 2100. 

Design and Craftsmanship

The Royal Oak's design is distinguished by its signature octagonal bezel, secured with eight hexagonal screws, and an integrated bracelet that exemplifies Audemars Piguet's dedication to superior craftsmanship. The 18-carat pink gold case and bracelet are meticulously hand-finished, showcasing a blend of satin-brushed and polished surfaces that enhance the watch's luxurious appeal. The blue dial, featuring the "Grande Tapisserie" motif, provides a striking contrast to the warm tones of the pink gold, while the subdials and inner bezel are rendered in the iconic "Night Blue, Cloud 50" hue, paying homage to the original Royal Oak design. 

Movement and Performance

At the heart of this timepiece lies the self-winding Caliber 5134, a movement renowned for its precision and reliability. Operating at a frequency of 2.75 Hz (19,800 vibrations per hour), it offers a power reserve of approximately 40 hours. The movement's perpetual calendar complication accounts for the varying lengths of months and leap years, ensuring accurate timekeeping without manual correction for decades. Additionally, the moon phase indicator adds a poetic touch, displaying the lunar cycle with remarkable accuracy.

• Week Indicator: A central hand points to the week numbers around the dial's periphery, providing an additional layer of temporal information.

• Leap Year Indicator: A discreet subdial indicates the current year within the leap year cycle, a testament to the watch's intricate engineering.

• Moon Phase Display: Positioned at 6 o'clock, the moon phase aperture showcases a meticulously detailed lunar depiction, enhancing the watch's celestial charm.
