The Audemars Piguet Royal Oak Concept was first launched in 2002 as ref. 25980AI.OO.0003SU.01 to celebrate the 30th anniversary of the launch of the iconic Royal Oak in a limited edition of 150 pieces. That first Royal Oak Concept, was fitted with an ultra rare sculpted-shaped case made of Alacrite 602 with a hardness of 430 vickers and a titanium bezel. The Alacrite 602 is a super-alloy composed of 57% cobalt, 31% chrome, 5% tungsten and the remaining 6% of carbon, silicon and iron.
While the first Royal Oak Concept did feature a tourbillon, it didn't come with a GMT function. Alternatively, it was equipped with a dynamograph, a power reserve indicator showing the number of turns of the barrel and a Kevlar aramid fiber strap.
