Masterfully skeletonized entirely by hand, the Royal Oak Offshore Tourbillon Chronograph is dedicated to the watch retailer, Ali Bin Ali, in Qatar. The extraordinary openwork, and the mechanical artistry and kinetic dance it reveals, is breathtaking. An item that will leave any passionate watchmaking connoisseur speechless and surely captivate anyone else, this extraordinary special edition chronograph timepiece from Audemars Piguet exhibits the intriguing inner dynamics of the majestic hand-skeletonized mechanical movement and its spectacular tourbillon while retaining excellent legibility of its useful functions. With bezel, screw-locked crown and push-pieces in black ceramic, the 44mm titanium case features glareproofed sapphire crystal front and back, providing 100m water resistance and mounted onto a black rubber strap with titanium tang buckle. Visible both through the openworked dial and transparent case back, the hand-wound 2936 caliber boasts 28 jewels and beats at 21,600 vibrations per hour, offering a power reserve of 72 hours. While the tantalizing tourbillon dominates the sight at the six o'clock position, the black dial with tachymeter scale on the flange and luminescent coating on white gold Royal Oak hands and hour-markers shows central hours, minutes and chronograph seconds, displaying small seconds and 30-minute counter at nine and three o'clock respectively.
