Among the most coveted references from Audemars Piguet, the Royal Oak Perpetual Calendar 25829ST holds a special place. This rare collector's item reveals its entire AP 2120/2802 manufacture caliber through a skeletonization entirely crafted by hand. The 39mm octagonal steel case houses a complete perpetual calendar (date, day, month, leap year, and moon phase), while the sapphire case back extends the mechanical spectacle. Offered in excellent condition with its complete set including box, papers, and archive extract, this piece underwent a full service in 2025.
L'Écrin Genève selects, authenticates, and services each watch with the utmost rigor. This Audemars Piguet Royal Oak Skeleton comes with a one-year warranty, for a worry-free purchase.
