Catalogue Note:
Spectacular to look at, the present example of the Quantieme Perpetual would fully express the extravagant watchmaking qualities of Audemars Piguet. Specializing in astronomical watches and clocks ever since 1875, the brand would continue to produce phenomenal timepieces such as the present example, featuring a mechanical perpetual calendar movement fully skeletonised to express its intricacy. It is equipped with one of the most famous pocket watch movements from the 80s to 90s - the calibre 5020, which was reworked to a perpetual calendar in 1982. To the best of our knowledge, not more than 50 examples were skeletonised for the perpetual calendar calibre 5020. Truly an amazing treasure, the present watch would make a terrific addition for any watch collection.
