Audemars Piguet 25594BA Royal Oak Day Date Moonphase 18K YG Champagne Dial

Crafted in the late 1980s to early 1990s, the Audemars Piguet Royal Oak reference 25594BA is a rare and sophisticated iteration of the iconic Royal Oak line. This 36 mm solid 18K yellow gold model houses a self‑winding movement—Caliber 2224/2825—offering day, date and moonphase complications in a harmonious, balanced layout. The champagne “Petite Tapisserie” dial, with its integrated sub‑dials at 9, 3 and 6 o’clock, presents a refined aesthetic that blends practicality with elegance. Produced in limited numbers (approximately 1,500 pieces), this reference stands out for its luxurious full‑gold construction and collector‑appealing complexity. As one of the earliest Royal Oak models to incorporate a moonphase, it represents a pivotal moment in the evolution of the line. Its proportions remain faithful to Gerald Genta’s original vision, offering a slim profile and integrated bracelet that wear with exceptional comfort. The combination of complications, gold execution and restrained size make this a highly sought‑after vintage piece among connoisseurs of horological craftsmanship. Excellent Condition with Audemars Piguet papers dated 1987.
