The Royal Oak Offshore was designed by Emmanuel Genta and was inspired by a vintage diving helmet. The 26470ST is a more aggressive and durable version of the Royal Oak that's suitable for swimming and light diving.

2014 marks a new beginning for Audemars Piguet’s Royal Oak Offshore – a watch that first burst into the traditionally conservative luxury-watch scene in 1993. The new series is still as innovative, forward-thinking and rebellious as its predecessors.

The “piece de resistance” of the 2014 update is the view offered on the in-house movement. When turning your ROO, you know that you’re really part of the family now (you finally have access to the Bro Code) as the new Royal Oak Offshore Chronographs are equipped of a sapphire case back. It allows you to look at the gold oscillating weight, the “Côtes de Genève” finishing and the polish beveled angles of the bridges.

The engine of the ROO Chronograph is AP caliber 3126. This is not an integrated chronograph movement, as it uses a Dubois-Depraz module, however the base movement is an Audemars Piguet movement. The 3126 is equipped with a hack system to stop the seconds when the crown is pulled out, a Gyromax balance and offers 55 hours of power reserve.
