Audemars Piguet Royal Oak Extra-Thin Yellow Gold — Petite Tapisserie Yellow Dial | Ref. 15202BA.OO.1240BA.02

When Audemars Piguet introduced the Royal Oak Jumbo in 1972, Gerald Genta's 8 mm-thin case was considered an engineering marvel — and the legacy of that original Extra-Thin lives on uninterrupted in the ref. 15202BA. Produced in yellow gold between 2012 and 2022, this 39 mm iteration occupies a distinguished chapter in the Jumbo lineage, widely regarded as the purest distillation of Genta's original vision. Offered complete with box and papers, it arrives as a complete collector's acquisition.

The heart of the ref. 15202 is Calibre 2121, the legendary ultra-thin automatic movement developed in collaboration with Jaeger-LeCoultre. At just 3.05 mm thick, Cal. 2121 remains one of the thinnest automatic calibres ever produced, delivering a 40-hour power reserve with a micro-rotor that preserves the dial's proportions. The warm yellow gold dial — dressed in the fine Petite Tapisserie guilloché — offers a tonal harmony with the 18-carat yellow gold case and integrated bracelet that few luxury sports watches can match. A date aperture at 3 o'clock provides functional elegance without disrupting the dial's clean architecture.

With the 15202 series now discontinued, secondary-market demand has only intensified — yellow gold examples with original papers represent a particularly coveted configuration. The AP folding clasp secures an integrated yellow gold bracelet of extraordinary fit and finish, a reminder that this watch is not merely a timepiece but a wearable artefact of the golden age of haute horlogerie.
