A Legacy in Openwork.

For the true collector, a timepiece must offer more than function or mere luxury — it must represent heritage, mastery, and permanence. The Audemars Piguet Perpetual Calendar Ref. 25892BA embodies these ideals with rare distinction.

Crafted in 18-carat yellow gold, this reference houses one of the most revered complications in horology: the perpetual calendar. It effortlessly tracks the irregular rhythm of the Gregorian calendar. But it is the execution, not merely the complication, that elevates this piece.

The skeletonized dial reveals the full architecture of this beautiful movement, offering an unobstructed view into the mechanism’s perpetual dialogue with time. Behind the openworked façade lies the soul of Swiss watchmaking: an ultra-slim automatic movement that accounts for the complexity of leap years, day, date, month, and moon phase. Each bridge and wheel is hand-finished to exacting standards, reflecting the maison’s commitment to both artistry and precision. The transparency invites contemplation — not only of its mechanical intricacy but of the centuries of horological evolution it represents.

Worn discreetly, yet constructed with undeniable presence, the 25892BA is not intended for fleeting admiration. It is a piece for the collector who understands that true value lies in craftsmanship, legacy, and the quiet authority of uncompromising design. Housed in a 39mm case that radiates old-world grandeur and modern technical brilliance. Dating back to 2007 and coming with its extract of the archive.
