Audemars Piguet Diver

The Audemars Piguet Royal Oak Offshore Diver 15720CN.OO.A002CA.01 has a 42 mm case in 18-carat white gold. The case measures 14.2 mm thick, and the dial sits under a sapphire crystal. Inside is the self-winding calibre 4308, visible through the case in a black finish that pairs with the dial colour. This dive time measurement watch also gives central seconds and a date display, and is a limited edition, one of 300 pieces made. It comes on a black rubber strap fitted with an 18-carat white gold pin buckle, part of an interchangeable strap system that includes an additional beige calfskin option. The case holds a 300 metre water resistance rating, well suited to the diving function it is built for.
