Few names in luxury watchmaking are as revered as Audemars Piguet. The Swiss luxury manufacture has been family-owned since its inception in 1875, and has become renowned for mechanically precise movements and avant-garde aesthetics. The company built a reputation for inventiveness when they unveiled the first minute repeater wristwatch in 1892, and went on to pioneer the jumping seconds hand pocket watch and the first ever skeleton watch. Their most characteristic creation, the extraordinary Royal Oak, was designed by legendary stylist Gérald Genta in 1972. Taking its inspiration from vintage diving helmets, with eight visible screws on the unorthodox octagonal bezel, the Royal Oak has come to define the brand and its identity—striking, unconventional and iconic. For the best deals, take a look at our list of used Audemars Piguet for sale.
