Audemars Piguet 25777BA Millenary Perpetual Calendar 18K Yellow Gold White Dial

The Audemars Piguet Millenary Perpetual Calendar ref. 25777BA, crafted circa 2000, stands as a singular expression of the Maison’s daring oval case design married to haute horology. Encased in 18K yellow gold, this automatic perpetual calendar is powered by the legendary Caliber 2120, a 36‑jewel self‑winding movement celebrated for its ultra‑thin architecture and technical refinement. The off‑centered white dial presents a harmonious and balanced layout, reflecting both elegance and functional clarity. Measuring approximately 41 mm lug‑to‑lug and 39 mm in width, the watch wears with a presence that is bold yet refined—a testament to its collector appeal. Though not a limited edition per se, its production in the early 2000s and the complexity of its perpetual calendar movement render it rare in today’s market. The Millenary line itself is renowned for its sculptural aesthetics and avant‑garde approach, and this reference encapsulates that spirit while offering one of AP’s most respected complications. Its Caliber 2120 movement links it to the brand’s storied tradition of ultra‑thin automatic calibers, enhancing its desirability among seasoned enthusiasts. In sum, the 25777BA is a compelling blend of architectural audacity, mechanical sophistication, and understated luxury—an ideal acquisition for the discerning collector. Excellent Condition with EWC Leather pouch, and undated papers.
