Music producer, rapper Peggy Gou spotted wearing a Audemars Piguet

DJ and music producer Peggy Gou recently showcased a striking example of Audemars Piguet's technical innovation: the Royal Oak Double Balance Wheel Openworked in 37mm yellow gold (Ref. 15467BA.OO.1256BA.01). The watch, captured on the wrist in an automotive setting, demonstrates how Audemars Piguet continues to evolve the Royal Oak collection beyond its iconic octagonal silhouette into territories of mechanical experimentation.

The defining feature of this reference lies within Calibre 3132, an in-house manufacture movement that departs radically from conventional watchmaking architecture. Unlike traditional watches with a single balance wheel, the Royal Oak Double Balance Wheel integrates two balance wheels positioned on the same axis, each oscillating at 4 Hz. This dual-balance architecture serves a dual purpose: it theoretically improves isochronal performance and rate stability across the power reserve curve, while simultaneously creating a mesmerizing visual effect through the skeletonized dial. The movement operates at 28,800 vibrations per hour and delivers approximately 70 hours of power reserve. The case measures 37mm in diameter—a deliberate nod to accessibility within the Royal Oak family—and features Audemars Piguet's characteristic integrated bracelet in matching yellow gold, with the signature octagonal bezel, screwed case back, and 50 meters of water resistance.

Within collector circles, the Royal Oak Double Balance Wheel Openworked represents a watershed moment for the brand. Rather than pursuing complications typical of haute horlogerie, Audemars Piguet chose to expose the movement itself as the ultimate complication. The skeletonized dial reveals the intricate geometry of Calibre 3132 in its entirety, transforming horological theory into visual performance. This reference launched in 2020 and remains in limited production, with yellow gold variants commanding particular desirability among collectors seeking alternatives to stainless steel or rose gold iterations.

Peggy Gou's choice reflects a broader trend among contemporary music industry figures toward high-watchmaking mechanics over logo-driven luxury. The pairing of the Royal Oak Double Balance Wheel with her personal aesthetic—marked by understated luxury and technical precision—underscores how Audemars Piguet has successfully repositioned the Royal Oak beyond sport-watch heritage into the realm of wearable sculpture. The 37mm size, often dismissed as "feminine-oriented," has gained momentum among collectors of all backgrounds seeking proportions that complement modern dress codes without sacrificing presence.

Retail pricing for the Audemars Piguet Royal Oak Double Balance Wheel Openworked 37mm in yellow gold stands at approximately €94,600 (roughly $103,000 USD), though supply constraints have historically elevated grey-market values. The watch remains subject to waitlists at authorised retailers, reflecting sustained demand for skeletonized Royal Oaks and Audemars Piguet's measured production strategy. Pre-owned examples trade at modest premiums above retail, indicating collector confidence in the reference's technical significance and long-term appeal within the expanding landscape of contemporary haute horlogerie.
