The legacy of Audemars Piguet’s perpetual calendar wristwatch began in 1955 when they had produced the world’s first ever perpetual calendar wristwatch with the essential leap year indication. However, it was not until 1984 when Audemars Piguet had finally combined its renowned perpetual calendar movement with its highly popular Royal Oak collection. . The present watch is a new version of the Royal Oak Perpetual Calendar in stainless steel. Made for a Hong Kong retailer, it is the first of its kind as it stands out not only with an indifferent majestic Grande Tapisserie green dial, but also featuring a new self-winding caliber 5134 that enhances the efficiency and reliability of the watch. First time ever to be in auction, the piece is estimated at HK$ 1- 2m / US$ 128,000 – 255,000. . audemarspiguetsavoirfaire #SothebysWatches #audemarspiguet #audemarspiguetroyaloak #audemarspiguewatch #WatchesofInstagram #WatchCollector #watchgeek #watches #perpetualcalendar
