Audemars Piguet - Royal Oak Concept Watch
The Royal Oak Concept watch took Audemars Piguet more than two years to produce because of its tedious technology involved both in its movement and design. It is a mechanical and manual-winding tourbillon. The finishing is fully by hand to complete its chamfered and sapphire-blasted plates, bars and bridges in its movement.
It case is made of Alacrite 602 which is an alloy of cobalt, chromium, and tungsten used widely in the aeronautical industry. The bezel is made of titanium and the case is made to resist pressure up to 50 bar and a water resistance up to 500m.
