The Royal Oak Offshore Tour Auto 2010 Chronograph is driven by selfwinding Calibre 2326/2840, featuring a 38-hour power reserve and a balance oscillating at 28,800 vibrations per hour. All parts of this “chronograph” movement are entirely decorated by hand. The main plate is rhodium-plated, bevelled and circular-grained, and the bridges are adorned with a Côtes de Genève motif. The watch displays the hours, minutes, seconds and date. It is also 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 chequered flag that is waved at motor-race finishes.

The 42 mm-diameter steel case is topped by a bead blasted bezel. The case assembly screws are also in polished steel, while the screw-lock crown and pushers are in black rubber. The caseback is engraved with the “Tour Auto” logo and bears the legend “Royal Oak Offshore – Serie Limitee”.

Its anthracite dial with the exclusive “Mega Tapisserie” finish carries red and silver-coloured counters, along with luminescent hands and numerals. Finally, this new chronograph is fitted with a black handsewn perforated leather strap and presented in a box also dedicated to motor sports, since it is shaped like a Ford GT 40 petrol cap.
