Jules Audemars and Edward Piguet were both in their early twenties when they founded Audemars Piguet in 1875. In 1972 AP launched a line of mechanical watches with hexagonal screws that fastened a porthole-like bezel. Thus was born the Royal Oak, in honor of the British Royal Navy/'s line of ships bearing the same name. The Royal Oak is among many of the most specialized and complex watches produced by this famous manufactory.
