Audemars Piguet is famous for its various inventions and complications in the watch industry. Founded in 1875, the Vallee de Joux company is credited with the smallest repeater (1891), the first skeleton watch (1928), the flattest automatic movement at 2.45mm (1967) and more ground-breaking calibres and movements. Audemars Piguet mens collections include the Royal Oak, Royal Oak Offshore, Jules Audemars, Edward Piguet, Classics and Millenary. The Royal Oak became the prototype of opulent sport watches. Recently Audemars Piguet unveiled its Royal Oak Offshore Pride of Siam, calibre 3126/3840 in Thailand. Even Jay-Z and Usher are sporting Royal Oak Offshore.
