Audemars Piguet Royal Oak 15407OR.OO.1220OR.01 Double Balance Wheel Openworked Rose Gold

The Audemars Piguet 15407OR.OO.1220OR.01 is a visually commanding take on the brand’s groundbreaking double balance wheel architecture, crafted entirely in 18k rose gold and paired with a dramatic dial. Measuring 41mm, the case showcases the Royal Oak’s iconic features—octagonal bezel with eight white gold screws, integrated bracelet, and a seamless mix of brushed and polished surfaces that highlight the warmth and richness of the rose gold.

At the heart of this reference is the Caliber 3132, a manually decorated selfwinding movement featuring twin balance wheels and double hairsprings mounted on the same axis, a patented innovation that enhances accuracy and stability by synchronizing their oscillations. The openworked bridges are rendered in a contrasting dark slate grey, exposing the mechanics of the gear train, barrel, and dual balance wheels with symmetrical precision. The sapphire caseback reveals more of the movement's high-end finishing, including polished angles and Côtes de Genève.

With its high-horology engineering and full precious metal construction, the 15407OR.OO.1220OR.01 is a bold expression of both technical mastery and aesthetic refinement—making it a centerpiece for collectors drawn to the mechanical soul of the Royal Oak.
