The Audemars Piguet Royal Oak Offshore Diver was originally launched in 2012 under reference 15703ST.OO.A002CA.01 and it quickly became a favorite amongst many AP collectors. Not only the AP Diver was yet another milestone in the evolution of the Royal Oak Offshore collection, but it also established itself as the new entry level watch —regardless of being priced higher than the Royal Oak 15400ST— for those wanting to get their feet wet for the very first time in the AP waters.
