The Audemars Piguet Royal Oak Quantième Perpétuel has been one of the brand’s most admired and sought-after models since the mid-1980s. While most examples were produced with either a 36 mm or 39 mm case, the present example, reference 25800ST, was designed with a refined 33 mm stainless steel case, offering a perfect blend of elegance and wearability.

First introduced in 1996, this reference is among the smallest perpetual calendar wristwatches ever produced, striking a harmonious balance between sophisticated design and excellent legibility.

At its heart is the ultra-thin caliber 2141/2806, specifically developed to accommodate the watch’s smaller dimensions. This particular example remains in excellent overall condition.

Additionally, it is accompanied by an extract from the Audemars Piguet archives, certifying its original sale in the year 2000.
