Audemars Piguet Royal Oak Yellow Gold — Openworked Double Balance Wheel Skeleton Dial | Ref. 15407BA.OO.1220BA.01

To combine the Royal Oak's most iconic silhouette with a fully openworked dial in 18-carat yellow gold is to make a statement of absolute confidence. The 15407BA does precisely that — the 41 mm octagonal case, resplendent in warm yellow gold with its characteristic alternating polished and brushed surfaces, frames a skeletonised view of the Double Balance Wheel Openworked calibre that has become one of AP's most celebrated contemporary achievements. Applied index hour-markers in gold punctuate the openwork with navigational clarity.

Calibre 4302 powers this reference, its twin balance wheel — the brand's patented innovation for enhanced regulation stability — displayed proudly at the centre of the skeletonised movement. The double balance wheel's two escapements work in concert to compensate for positional errors, delivering chronometric performance that matches the aesthetic drama on display. A screw-down crown ensures the case's 50-metre water resistance is maintained across the full integrated yellow gold bracelet.

The exhibition caseback transforms even the reverse of this watch into a horological spectacle, revealing the movement's finishing and the rotor's sweep. Fastened by AP's folding clasp, the integrated bracelet achieves the seamless visual flow that defines the Genta aesthetic at its most luxurious. For collectors who require their horology to announce itself without equivocation, the 15407BA in yellow gold represents the Royal Oak's personality at full amplitude — opulent, technical, and wholly irreplaceable.
