Introduced in 1998, the Audemars Piguet Royal Oak Perpetual Calendar Ref. 25820SP represents a significant evolution in the lineage of the Royal Oak Perpetual Calendar. Most notably, it introduced the leap year indication—a crucial refinement over its predecessor, the Ref. 25654—enhancing the practicality of its already sophisticated perpetual calendar mechanism.
Housed in a 39mm stainless steel case with a platinum bezel, this reference maintains the Royal Oak’s iconic balance of sportiness and elegance. The watch is powered by the ultra-thin Caliber 2120/2802, an automatic movement derived from the renowned Jaeger-LeCoultre Caliber 920, which seamlessly manages the display of the day, date, month, moon phase, and leap year cycle.
The Tapisserie dial, a signature feature of the Royal Oak collection, enhances the visual depth while ensuring excellent readability. The contrast between the steel case and platinum bezel adds a touch of understated luxury, making this timepiece a rare and coveted collector’s piece.
As a milestone in Audemars Piguet’s history, the Ref. 25820SP not only refines the perpetual calendar complication but also upholds the innovative spirit of the Royal Oak collection.
