The latest Audemars Piguet Royal Oak is more than a stunning timepiece. This Swiss-made, modern design is also recognised as a record holder, becoming the world’s thinnest automatic perpetual calendar watch. With a movement of just 2.89 mm in thickness and a case of 6.3 mm in height, the new Royal Oak Selfwinding Perpetual Calendar Ultra-Thin lives up to its lengthy name.
To achieve the ultra-thin design, all three perpetual calendar functions have merged into one single layer. The day, date and month subdials are also enlarged over previous Royal Oak Perpetual Calendar models for optimum legibility.
The night and day indication at 8 o’clock has been added symmetrically to the leap year indicator positioned at 4 o’clock. Featured above all three dials is the moonphase indicator.
Evolving from the initial RD#2 prototype presented at SIHH 2018, the Royal Oak Selfwinding Perpetual Calendar Ultra-Thin combines titanium and 950 platinum for an elegant look and a significantly lighter feel on the wrist. Alternating polished and satin-brushed surfaces adorn the case, bracelet and bezel.
The dial is no longer endowed with a blue “Grande Tapisserie” pattern. Instead, its blue satin finishing adds to the enhanced legibility as well as the watch’s refined aesthetics.
The movement is Audemars Piguet Calibre 5133, and the case has a 41mm diameter. The power reserve comes in at 40 hours. Glareproofed sapphire crystal protects the dial and caseback, along with a titanium screw-locked crown that offers water-resistance up to 20 metres. White gold is applied to the hour-markers, and the Royal Oak hands possess a luminescent coating for reading the dial in the dark.
Audemars Piguet is the oldest fine watchmaking manufacturer still in the hands of its founding families. Since 1875, the company has released an abundance of premium watches with the new Royal Oak Selfwinding Perpetual Calendar Ultra-Thin just the latest in a long line of world firsts.
