Manufactured in 2002 to commemorate the 30th anniversary of the iconic Royal Oak collection, the Audemars Piguet Royal Oak Concept was considered a radical re-interpretation of the original designs of Gerald Genta. The Royal Oak Concept Watch’s case is made from Alacrite 602, an innovative and durable alloy consisting of cobalt, chrome, tungsten and traces of carbon, silicon and iron, with purposes in the aerospace industry and medical applications and represent the first timepiece ever produced with this particular material. Developed in only 150 examples, the timepiece features a skeletonized dial encompassing a complex tourbillon mechanism with a vertical in-line power reserve and dynamograph indicator developed by AP’s complication specialists Renaud et Papi. At the 12 o’clock position, Audemars Piguet added a “dynamographe” to represent the quality of torque on the mainspring, and to its right is a unique linear power reserve spanning the length of the dial from 1 o’clock to 5 o’clock. At 6 o’clock, a function selection indicator showing the current function of the crown: winding (R-remontoir), neutral (N-neutre) and setting (H-heures). Through the screw down push button below the crown found on the case at 4 o’clock, the watch is set to the desired function in order to wind or set the time. Through its surprising design, groundbreaking case materials and strong heritage, the present timepiece is also offered with its original papers.
