Audemars Piguet's Royal Oak Perpetual Calendar reference 25820ST.OO.0944ST.04 stands as one of the most elegant and technically accomplished interpretations of the brand’s storied QP lineage.
Introduced in the 1990s and produced until the early 2000s, this reference channels the original spirit of Gérald Genta’s groundbreaking Royal Oak design, while seamlessly integrating the complexity of a perpetual calendar complication.
Housed in the signature 39mm stainless steel case—the so-called “Jumbo” size—this piece features a striking blue “Grande Tapisserie” dial, harmoniously laid out with four symmetrically placed subdials displaying the calendar indications and a beautifully rendered moonphase at 6 o’clock.
The Calibre 2120/2802, one of the slimmest full rotor perpetual calendar movements ever made, offers exceptional finesse in both performance and form.
With its razor-sharp bevels, satin finishing, and iconic octagonal bezel secured by white gold screws, the Royal Oak ref. 25820ST is a definitive grail for collectors who value the synthesis of design, mechanical mastery, and historic significance. This example offers collectors a rare opportunity to acquire one of the earliest and most balanced executions of the perpetual calendar within the Royal Oak line—before the bold upsizing of later generations.
Don’t miss this extremly rare blue dial and well kept collectors AP - clearly an investment piece as well.
