Audemars Piguet Diver

Audemars Piguet's Royal Oak Offshore Diver 15710ST.OO.A085CA.01 is a steel watch measuring 42 mm across. The case runs 14.1 mm thick and carries a sapphire crystal over a beige dial. Inside is the self-winding calibre 3120, which drives the hours, minutes, centre seconds and date. The date sits in its own window, and the centre seconds hand sweeps continuously to mark running time. Both functions stay legible against the beige dial finish. A beige rubber strap closes with a steel pin buckle. Built as a dive watch, the case is rated to withstand depths of 300 metres, a figure the steel construction and screw-down elements are designed to hold.
