The Royal Oak Offshore Tour Auto 2010 Chronograph is a limited edition of 60 examples world wide, driven by AP’s selfwinding, hand-decorated Caliber 2326/2840. 
The watch is equipped with a chronograph function with central seconds hand along with 30-minute and 12-hour counters. 
The tachometric scale on the inner bezel ring, decorated with alternating black and white squares, evokes the chekered flag that is waved at motor-race finishes.
Water resistant to 100 meters / 330 feet
