Audemars Piguet Diver

Audemars Piguet's Royal Oak Offshore Diver 15720ST.OO.A403CA.01 is a 42 mm steel dive watch. The case measures 14.2 mm thick and the dial sits under a sapphire crystal. Selfwinding calibre 4308 drives the watch, showing central seconds and the date along with dive time measurement. The dial is blue, matched to an abyssal blue rubber strap. A stainless steel pin buckle closes the strap. Audemars Piguet built this reference for diving, and it shows in the dedicated timing function. The case is rated to 300 metres, appropriate for a dive watch of this type.
