About this watch

The Audemars Piguet Royal Oak Perpetual Calendar Openworked Pink Gold is a masterpiece that encapsulates the essence of luxury watchmaking. This remarkable timepiece features an 18-carat pink gold case, measuring 39.00 mm in diameter and 9.30 mm in height, exuding warmth and luxury. The openworked design reveals the intricate inner workings, showcasing the complex mechanics within. At its heart lies the Audemars Piguet caliber AP 2120 / 2802, an automatic movement celebrated for its extra-thin design and precision. With a 40-hour power reserve and 38 jewels, this movement is a testament to the brand's meticulous attention to detail. The perpetual calendar automatically adjusts for month lengths and leap years, while the moonphase complication adds an astronomical element to this impressive watch. Sapphire crystal glass protects the dial, enhancing visibility of the intricate skeleton design. With a water resistance of 20 meters, this watch can withstand splashes but is not designed for deep-sea diving. The manual finishing of the bridges features polished bevels, satin-brushed edges, and perlage on the recesses, accentuating the watch's exclusivity.
