The Royal Oak is considered to be the most popular watch that Audemars Piguet currently manufactures. It was first presented at the 1972 Baselworld, during the quartz crisis. Designed by Gérald Genta, who is also responsible for designing other notable timepieces including the Patek Phillipe Nautilus, the Royal Oak model is considered to be the first luxury sports watch in the world. The watch was inspired by traditional diving helmets and therefore featured exposed screw heads as well as a unique case design. The watch also featured an integrated bracelet.
