This Audemars Piguet Quantième Perpétuel stands out with a striking mother of pearl dial. Within this reference, only 29 pieces were made in rose gold, and we can reasonably assume that a select handful within that number bear a stone dial. Turning over the watch reveals a skeletonised rotor through a sapphire caseback. This piece is an excellent choice for anyone looking to add an exceptional neo-vintage watch to their collection.


In the late 1970s, complicated wristwatches were exceedingly rare. The Quartz Crisis had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600. Against all odds, three watchmakers at Audemars Piguet decided to develop the world’s thinnest automatic perpetual calendar movement. The project was carried out in secret, with the manufacture’s upper management completely unaware of what was going on. The watchmakers worked in their free time, often meeting at night to discuss their work.

In 1977, they surprised Georges Golay, the CEO of Audemars Piguet at the time, with the finished calibre. A risk taker who’d already released the Royal Oak a few years prior, Golay was confident that the manufacture could successfully commercialise the automatic perpetual calendar. When it was launched in 1978, the Quantième Perpetuel was the world’s thinnest automatic perpetual calendar. To put things in perspective, in 1984, only 1,066 perpetual calendars were produced in Switzerland. Of those, Audemars Piguet made 675.
