Audemars Piguet Royal Oak Double Balance Wheel Openworked 15407BA.OO.1220BA.01 from December 2024 Audemars Piguet Royal Oak Double Balance Wheel Openworked ref. 15407BA.OO.1220BA.01 in 18K yellow gold with fully openworked movement and integrated gold bracelet. One of the most technically interesting modern Royal Oak models, where the movement itself becomes a major part of the design and the double balance wheel system is visible directly from the dial side. The case measures 41mm and 10.1mm in thickness and is made in 18K yellow gold with anti reflective sapphire crystal and sapphire caseback. The openworked construction gives a clear view of the bridges, gear train and double balance wheel, while the yellow gold hour markers, hands, case and bracelet create a strong contrast against the darker movement. Inside is the Audemars Piguet Caliber 3132, an automatic openworked movement with double balance wheel system, centre seconds and approximately 45 hours of power reserve. The construction uses two balance wheels and two hairsprings mounted on the same axis to improve stability and precision. This example was originally sold in December 2024 and comes with boxes, certificate and extra links.
