Estimate: € 40.000 –⁠ 80.000

Produced between 1985 and 1994, this reference 25661BC introduced advancements such as a sapphire crystal case back, allowing a clear view of the beautifully finished automatic movement—a feature that set it apart from earlier references like the 25 657. With its meticulously sunken sub-dials displaying day, date, month, and moon phase, the watch embodies both technical complexity and understated elegance. The production of reference 25 661 was extraordinarily limited, with only 342 pieces crafted in total. Among these, just 32 were made in white gold, making this version exceedingly rare. The salmon-colored dial further enhances its exclusivity, offering a warm and sophisticated aesthetic that contrasts beautifully with the white-gold case. The significance of this particular piece is amplified by its status as the first in production, numbered 001, a detail that holds immense importance for collectors, especially given the limited production numbers. This combination of rarity, craftsmanship, and historical significance makes the Audemars Piguet Quantième Perpétuel 25661BC with salmon dial a true masterpiece, representing the pinnacle of haute horology and an unparalleled opportunity for connoisseurs.
