Reference: 220.10.41.21.03.002
The Audemars Piguet Royal Oak Double Balance Wheel Openworked 15412BC Blue Sapphire Bezel is a rare and visually striking interpretation of one of Audemars Piguet’s most technically advanced timepieces.
Crafted in solid 18K white gold, this 41mm Royal Oak is elevated by a factory-set baguette-cut blue sapphire bezel—adding a bold yet refined contrast to the fully openworked dial. The deep blue tones continue throughout the piece, with matching accents on the inner flange and movement components, creating a cohesive and highly collectible aesthetic.
At the heart of the watch is Audemars Piguet’s patented double balance wheel system, designed to enhance precision and stability by improving the oscillator’s performance. Fully visible through the skeletonized dial, this mechanism offers a mesmerizing display of symmetry and mechanical artistry.
The openworked movement is meticulously hand-finished, revealing intricate bridges, gears, and balance architecture—blending high horology with contemporary design. Paired with the iconic integrated white gold bracelet, this piece delivers both presence and technical mastery.
Produced in extremely limited quantities, this configuration stands among the most desirable Royal Oak references for collectors seeking rarity, innovation, and visual impact.
