Audemars Piguet, the Swiss haute horlogerie manufacturer that is constantly researching materials, has launched its first alluvial gold watch. This new 18K gold alloy (a cross between white and rose gold) reflects light delicately, creating multiple expressions depending on the angle and light of the light. The watchmaker chose this new precious metal to create the 41 mm Royal Oak Skeleton Flying Tourbillon watch. In keeping with the case and bracelet, Caliber 2972’s skeletonized bridges and main plate are also coated with sand gold, while the multi-layered structure is distributed on both sides of the watch. This new electroplating color creates a subtle contrast with the rhodium-colored components inside the movement, creating a unique three-dimensional effect. The Royal Oak Flying Tourbillon Skeleton Watch is the perfect combination of complex technology and modern design.
