Audemars Piguet - Royal Oak Perpétuel Ref. 25654BA

The Audemars Piguet - Royal Oak Perpétuel Ref. 25654BA stands as one of the most refined and technically significant expressions of the vintage Royal Oak lineage. Produced in 1988, this timepiece masterfully combines Gérald Genta’s revolutionary sports design with watchmaking’s most prestigious complication: the perpetual calendar.

Crafted entirely in 18k yellow gold, this Royal Oak is distinguished by a striking champagne dial that gives the watch a warm, quintessential 1980s aesthetic. The 39 mm case retains its sharp edges and full proportions, preserving the unmistakable identity of the octagonal bezel with its signature exposed screws.

At its heart beats the caliber 2120/2800, a true landmark in horological engineering. Introduced in 1977, it was the world’s thinnest automatic perpetual calendar movement, measuring just 3.95 mm. This is a timepiece destined for seasoned collectors who value technical substance and heritage over fleeting trends.
