Introducing The Audemars Piguet Royal Oak Perpetual Calendar Openworked Black Ceramic

Following the Royal Oak Perpetual Calendar Black Ceramic presented in 2017, the Le Brassus manufacturer debuted a new open-worked version. The Royal Oak Perpetual Calendar Openworked Black Ceramic.

Measuring 41 mm x 9.9 mm, the case of the new Royal Oak Perpetual Calendar Black Ceramic Openworked is crafted from black ceramic, which features intricate satin-brushing on the entire case and bracelet, with the exception of the beveled edges of the case, bezel, caseback, and bracelet, which have been polished.

Underneath a sapphire crystal dial is in-house movement caliber 5135, beating at 19,800 vibrations per hour with a power reserve of 40 hours.  5135 has been extensively open-worked on the front and back, revealing the density of the mechanics inside the movement. Both the hands and applied hour markers are solid pink gold, and importantly, the movement has been dressed up to match.

The plate of the perpetual mechanism is skeletonised but also gilded in pink gold, leaving scattered traces of the rose alloy across the dial – arguably the most important aesthetic detail on the front.  The watch functions include hours, minutes, seconds, and a perpetual calendar (date, day, week, month, leap year, and moon phaseindicators).

The Audemars Piguet Royal Oak Perpetual Calendar Openworked ref. 26585CE.OO.1225CE.01 is a boutique exclusive with a price of Swiss Francs 130,000. Discover Opulent Club on Apple News.
