A contemporary icon that exemplifies Audemars Piguet’s mastery of technical complexity and design purity, the Royal Oak Double Balance Wheel Openworked Ref. 15407ST.OO.1220ST.02 is a standout creation in stainless steel. This 41mm reference combines the industrial beauty of steel with the mesmerizing architecture of a fully openworked dial, making it a bold statement for collectors and enthusiasts alike.

Crafted from brushed stainless steel, the case and integrated bracelet maintain the Royal Oak’s instantly recognizable form, complete with the signature octagonal bezel and exposed hexagonal screws. The finely finished surfaces contrast beautifully with polished bevels, showcasing AP’s exceptional attention to detail.

The star of this reference is the openworked slate grey dial and visible movement architecture, revealing the innovative Caliber 3132 — Audemars Piguet’s patented double balance wheel mechanism. By mounting two balance wheels and two hairsprings on the same axis, the system enhances precision and stability while offering a captivating mechanical display through the front and exhibition caseback.

This is a modern Royal Oak that wears its mechanics on its sleeve — a refined and technically advanced creation for those who value openworked movements and uncompromising finishing.
