Audemars Piguet 25654BA Royal Oak Perpetual Calendar 18K Yellow Gold Champagne Dial

The Audemars Piguet Royal Oak Perpetual Calendar in reference 25654BA.OO.0944BA.01 is a high-grade, full gold interpretation of the iconic Royal Oak design, built to impress even among serious collectors of vintage complications. The watch features a solid 18k yellow gold case and bracelet with the unmistakable octagonal bezel and signature exposed screws, delivering an aggressive yet refined presence on the wrist. The champagne dial is executed with a classic perpetual calendar layout, including day, date, and month indications, plus a moonphase for a complete, balanced calendar face. The dial has developed some aging and patina that is appropriate with its age and are original to the watch. Powering the watch is the Audemars Piguet automatic Caliber 2120/2800, a thin and respected movement architecture that is widely regarded for its reliability and finish. Offered with a matching champagne gold dial aesthetic, the overall color harmony makes the QP display especially legible and elegant in different lighting. For collectors, this reference stands out as a rare configuration of the Royal Oak family where the complication is integrated into the original Royal Oak DNA rather than a later design language. At 39mm with an ultra-slim profile for the complexity involved, it remains one of the most compelling ways to own a perpetual calendar from the brand’s formative Royal Oak era. Its 50m water resistance gives the piece a more practical edge than many dress-oriented vintage gold complications. Excellent Condition with European Watch Company leather travel pouch.
