Audemars Piguet. Unusual and Rare, Perpetual Calendar Open Face Pocket Watch, in Yellow Gold with Leather Pouch Model: Quantieme Perpetuel Pocket Watch Reference: 5537 BA Case Material: Yellow Gold Year: 1960s Movement: Manual Caliber: 17 SVFQ Case N°: 48805 Movement N°: 48805 Dimensions: 46 mm Signed: Dial, Case and Movement Accessories: Leather Pouch It was 1875 when Jules Louis Audemars joined forces with Edward Auguste Piguet. They worked together to develop watches equipped with complex mechanisms and precision still found in the watches today. Over the years Audemars Piguet has been a source of inspiration and an example for many watch brands due to the incredible innovations, it has been able to bring and for the large number of challenges it has faced. In 1957 was introduced the first Audemars Piguet wristwatch with a perpetual calendar and in 1967, the thinnest self-winding caliber with a central rotor was released at only 2.45 mm. This pocket watch perfectly represents that period using a typical art deco design with a beautiful yellow-gold case and lots of complications. Inside this piece is powered by a 17″ caliber which was produced in very few quantities and outside there is the heart of the watch: White dial with black baton indexes, blued hands, dates, month, day of week and moon phase indication. Precious jewel for its unique style, this watch is further proof of Audemars Piguet’s skill. Estimate € 30000 - 60000
