Calibre 5020 was in production for about 17 years (1979 - 1995). During this time, more than 1000 examples of the movement were produced - however only about 200 pieces were upgraded with the perpetual calendar module. Furthermore, only about one quarter of those (around 50 examples) featured the skeletonized construction. As these 50 skeletonized perpetual calendar calibres were used in different models, these numbers are already enough to give an idea of the scarcity of the present watch.
Beyond the rarity side of the equation, one cannot overlook the absolutely stunning aesthetics of the piece. While skeletonized timepieces tend at times to be difficult to read - especially when the dial, such as in this instance, provides more information than just the time - the adoption of blue chapter rings for the subsidiary counters renders reading the date an effortless endeavour. The same holds true for the time, with the large cathedral-style blued hands providing ideal contrast on the metal background. Also the placing of the hours on an outer track bordered by an additional minute blue track is an obvious effort for maximum legibility.
The final result is an absolute mechanical masterpiece. Offered in excellent condition and with its Audemars Piguet Certificate of Origin and Guarantee, presentation box and outer packaging, this watch will provide endless delight to its new owner.
Please note that the proceeds of the present timepiece will be donated by the consignor to various charities.
