Overview

The Audemars Piguet Royal Oak Double Balance Wheel Openworked 41 (ref. 15407ST) presents the iconic octagonal bezel and integrated bracelet of the Royal Oak in a fully skeletonised form, revealing Calibre 3132 in its entirety. The movement's defining feature is a double balance wheel that improves rate stability by compensating for positional errors. Introduced in 2016, the reference remains in production and represents one of the most technically ambitious expressions of the Royal Oak line.

History

Audemars Piguet introduced the Double Balance Wheel Openworked as part of a broader effort to bring in-house horological innovation to the Royal Oak's skeleton tradition. Calibre 3132 was developed to address the sensitivity of a conventional single balance wheel to gravitational and positional variation, pairing the twin-wheel architecture with an openworked plate that transforms the movement into the dial itself. The 41 mm stainless steel case of the 15407ST places the reference squarely within the contemporary Royal Oak sizing that collectors have embraced since the line's expansion in the 2000s and 2010s. The reference has maintained a consistent presence in the Royal Oak catalogue, cementing its status as a signature complication piece for the line.

Notable points

Calibre 3132 features a double balance wheel, a regulating organ designed to average out positional rate deviations across two coupled oscillators.
The openworked slate-grey dial eliminates the traditional dial plate, allowing an unobstructed view of the movement architecture from the front.
The 41 mm stainless steel case retains the Royal Oak's hallmark hand-finished alternating brushed and polished surfaces on the octagonal bezel and integrated bracelet.
Introduced in 2016, the 15407ST has remained a continuous production reference, reflecting sustained collector interest in skeletonised Royal Oak variants.
The movement finishing follows Audemars Piguet's established standards, with Côtes de Genève, bevelling, and anglage visible through the open architecture.
