Dial, case and movement signed. DIM. 44 x 57 mm. THICKNESS 18 mm. ROYAL OAK "CONCEPT" The "Concept" was produced in a limited edition of only 150 watches ? 30 PIECES IN 2002 ? 60 IN 2003 ? 60 IN 2004 At the time one of Audemars Piguet's most complicated watches and most innovative model. Entirely developed and built by AP's subsidiary Renaud & Papi, the "CW 1" concept watch celebrates 30 years of "Royal Oak" history and breaks new ground with its highly unusual technical features: electro-erosion formed titanium shock absorbers to protect the tourbillon cage; a clutch system with mode pusher and indicator to wind the watch or change the time; titanium movement plates, which are light yet strong and an innovative linear power reserve indicator, which is calibrated for the number of turns the barrel makes (one barrel rotation equals circa 6 hours of operation). The watch case is machined from Alacrite 602, a new super-alloy used in aero-technology and medical applications. It consists of 57% Cobalt, 31% Chrome, 5% Tungsten and trace amounts of Carbon, Silicon and Iron. The material is extremely hard (Vickers Rate of 430) and difficult to work with, especially on such a challenging case design like the "Concept" watch. The CW 1 gives testimony to Audemars Piguet's horological audacity and impressively highlights that after 30 years of production the iconic "Royal Oak" still continues to surprise with innovative features both technically and esthetically.
