Audemars Piguet Diver

Audemars Piguet Royal Oak Offshore Diver 15720ST.OO.A010CA.01 has a 42 mm steel case, 14.2 mm thick. The case carries a sapphire crystal over a black dial. Inside is the self-winding Calibre 4308, fitted with central seconds and a date function. This is a dive watch, built with the octagonal Royal Oak Offshore case in a form meant for real underwater use rather than as a styling exercise alone. It comes on a white rubber strap fitted with a stainless steel pin buckle, which allows the strap to be swapped out when needed. Audemars Piguet rates the case to 300 metres, in keeping with its purpose as a genuine diving instrument rather than a dressed-up sports watch.
