Description

The Audemars Piguet Royal Oak 15407ST.OO.1220ST.01 is a striking showcase of technical innovation and architectural watchmaking, executed in classic stainless steel with a fully openworked dial. Measuring 41mm, the case retains the Royal Oak’s iconic design elements—octagonal bezel with exposed screws, integrated bracelet, and a mix of brushed and polished finishing that enhances its geometric form. What sets this reference apart is the stunning display of the double balance wheel mechanism, introduced by Audemars Piguet to improve precision and stability. The openworked dial and movement bridges reveal a symmetrical, hand-finished landscape of gears, wheels, and twin balance assemblies, with the bridges treated in dark grey for striking contrast. The Caliber 3132, visible from both the front and sapphire caseback, features two balance wheels and two hairsprings mounted on the same axis, oscillating in harmony—a patented innovation designed to enhance chronometric performance. Blending bold aesthetics with horological ingenuity, the 15407ST is more than just a skeleton watch—it’s a high-performance, technically complex timepiece that remains deeply connected to the Royal Oak’s industrial-chic heritage. Ideal for collectors who appreciate both mechanical artistry and iconic design.
