Audemars Piguet Diver

Audemars Piguet's Royal Oak Offshore Diver 15720ST.OO.A052CA.01 has a 42 mm steel case, 14.2 mm thick. A sapphire crystal covers the green dial, and the case is fitted to a self-winding calibre 4308. The movement runs the date and central seconds functions, with dive time measurement built into the display. This is a dive watch, and its dial reads clearly against the khaki green tone AP has chosen for this reference. The rubber strap closes with a steel pin buckle and uses an interchangeable system, so it can be swapped for another strap without tools. Rated to 300 metres, the case holds up to the demands the Diver name implies.
