Audemars Piguet Royal Oak Chronograph 26317BC.OO.1256BC.01(Replique Montre Audemars Piguet Royal Oak), presents the legendary and iconic Royal Oak Chronograph with an 18K white gold case. The watch has a diameter of 38 mm and a thickness of 11 mm, with a light blue "Grande Tapisserie" dial and sub-dial and a dark blue scale ring.
The watch is equipped with Calibre 2385 self-winding movement, which is based on the legendary Frederic Piguet Calibre 1185 movement.

Calibre 2385 movement is assembled from 304 parts, containing 37 jewels and only 5.5 mm thick. It once held the record for the thinnest automatic mechanical chronograph movement and can provide a 40-hour power reserve. The 18K white gold case with anti-reflective sapphire crystal and screw-in crown is water resistant to 50 meters. The light blue dial is decorated with platinum fluorescent three-dimensional hour markers and hands, and is equipped with a 30-minute cumulative chronograph, small seconds and 12-hour cumulative chronograph at 3, 6, and 9 o'clock positions. The date window is set between 4 and 5 o'clock.
