Audemars Piguet Selfwinding Emerald "50th Anniversary"

Audemars Piguet's Royal Oak Selfwinding "50th Anniversary" ref. 15514BC.EE.1284BC.01 is a 41 mm white gold case, one of a set of ten pieces each decorated with a different gemstone. A sapphire crystal covers the green dial, which shows hours, minutes and centre seconds. The self-winding calibre 4309 drives the watch and carries an oscillating weight marked for the anniversary. The piece is set with diamonds, and the design carries 861 baguette-cut emeralds totalling around 32 carats. The bracelet is white gold and closes with a folding clasp. Water resistance is rated to 50 metres, modest given the weight of stonework across the case and bracelet.
