Audemars Piguet Royal Oak “Sand Gold” Skeleton

Audemars Piguet has introduced the Royal Oak Selfwinding Flying Tourbillon Openworked in a new proprietary 18ak gold alloy known as sand gold, which has a hue that’s somewhere between white and pink gold, thanks to the addition of more palladium than found in pink gold and less than in white gold.

Audemars Piguet’s automatic caliber 2972 which measures 31.5 mm x 6.2 mm, beats at 3Hz, powers the hours, minutes, and flying tourbillon. The movement was engineered from the ground up as a skeletonised caliber, as evidenced by the neat and tidy bridge layout. Once fully wound the 27-jewel caliber can run 65 hours autonomously, and is continually wound by wrist movement.

In addition, the other movement components present refined Haute Horlogerie decorations including satin, circular and sunray brushing, snailing, as well as polished chamfers. The polished V-angles that can be admired on both sides of the watch reflect the meticulous craftsmanship. 

The Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Openworked 18K Sand Gold (Ref. 26735SG.OO.1320SG.01) is water-resistant to 50 meters and retails for $250K.
