The new Royal Oak Selfwinding Flying Tourbillon Openworked in 41 mm introduces the very first timepiece crafted in sand gold, a new 18-carat gold alloy conferring rich plays of light. Hovering between white and pink gold, its colour changes depending on the angle and light, thus offering varied aesthetic possibilities.

To complement the new gold case and bracelet, Audemars Piguet developed a matching sand-gold-toned hue to adorn the openworked bridges and mainplate of Calibre 2972, whose multilayered architecture takes centre stage on both sides of the watch.

This new galvanic colour sits in subtle contrast with the rhodium-toned components of the movement’s inner workings to create a unique 3D effect. The result is a harmonious scene blending technical complexity with contemporary design.

Sand gold offers subtle variations depending on the light, provides resistance over time and making it both a durable and timeless colour.
