Audemars Piguet

The Royal Oak Perpetual Calendar debuted in 1983 as the reference 5554, later known as the 25554, marking Audemars Piguet’s foray into merging luxury with high complication.

Among the many iterations, the Audemars Piguet Royal Oak Perpetual Calendar reference 25636PT stands as a true collector’s piece. Faithful to the original Jumbo proportions, it features a 39 mm platinum case and a striking skeletonised dial revealing the intricate movement beneath. The blue subsidiary dials and outer track provide both visual contrast and enhanced legibility.

This rare platinum variant displays the day, date, astronomical moon phase, and month, with its transparent dial and blue accents offering a captivating view of the mechanics. The presence of the early “Audemars Piguet” signature further recalls the first executions of the reference.

Produced in a limited run of just 313 examples across all metals, with only 41 in platinum, the reference represents a remarkable convergence of rarity and craftsmanship, embodying Audemars Piguet’s bold fusion of sport and complication.

Preserved in excellent condition and likely worn only a handful of times, the present example shows virtually no signs of wear, with a tight bracelet and crisp surfaces, further enhancing its desirability among collectors.
