The present Audemars Piguet Quantieme Perpetual skeletonised pocket watch in 18K yellow gold is a signature of the Le Brassus based manufacturer. With a respected heritage in manufacturing some of the most impressive perpetual calendar timepieces, Audemars Piguet is notably distinguished for introducing the Royal Oak in 1972. Entering into the heights of the quartz crisis in the early 1980s, most manufacturers abandoned the production of mechanical timepieces and replaced them with quartz. However, that was not the case for Audemars Piguet. With a strong belief that the quartz wristwatch will not dominate traditional mechanical wristwatch, the firm continued to develop complicated perpetual calendar timepieces despite the fact that its competitors were shifting towards the new trend.

The present Audemars Piguet ref. 25559BA is an attractive statement piece from one of the most emblematic periods of horology. Fully skeletonized, the dial depicts the technical prowess of Audemars Piguet through the complicated cal. 5020/2820. With fully hand-engraved bridges, the combination of traditional artisanal craft and horological excellence is clearly presented in this present pocket watch. A wonderful and important era for Audemars Piguet and this present example from the respective era is offered in attractive overall condition and value.
