Audemars Piguet displayed watch making innovation and craftsmanship even during its early years, but probably one of its greatest achievements is the creation of the Royal Oak series. The Audemars Piguet Royal Oak collection is the first luxury steel sports series ever made. Its features and design are highly distinctive and the collection enjoys mass appeal among watch collectors worldwide. New watch models are continually being added to the Royal Oak and the Royal Oak Offshore collections. Audemars Piguel completely overshadowed other watch makers of its class with this creation.
