To celebrate the milestone 40th anniversary of Audemars Piguet’s Royal Oak timepiece, the iconic luxury watch brand is releasing the Openworked Extra-Thin Royal Oak Limited Edition 40th Anniversary in January.

As the first luxury sports watch ever, Audemars Piguet’s Royal Oak has become a legend. To celebrate the iconic timepiece’ 40th anniversary, the luxury watch brand is releasing the Openworked Extra-Thin Royal Oak Limited Edition 40th Anniversary in January.  This platinum anniversary edition is issued in a limited series of just 40.

As a specialist in ultra-thin movements, the Manufacture in Le Brassus chose this complex horological mechanism to power the very first Royal Oak in 1972. It was thus the famous Calibre 2121, one of the world’s thinnest mechanical selfwinding models at just 3.05 mm thick, that beat at the heart of the first versions of the Royal Oak. This distinctive expertise, consisting in engraving and hollowing out the movement to give it an airy character and play on its transparent effect, is an art still mastered by very few artisans. Combining within a single timepiece the constraints imposed by an ultra-thin movement and the demands of skeletonisation or openworking represents an impressive feat indeed.

The 39 mm diameter of this Openworked Extra-Thin Royal Oak is identical to that of the 1972 Royal Oak. Considered outsized and extravagant at the time of its launch, it shaped the trend for larger watches and now represents a medium-sized diameter. The platinum case is water-resistant to 50 metres and fitted with glareproofed sapphire crystals front and back. All the refined finishing and decoration of the movement may be admired at leisure. The new folding clasp, also in 950 platinum, is distinguished by a double safety fastening system.
