The Audemars Piguet Royal Oak Ref. 25860ST, affectionately known as the “Kasparov Chronograph”, is a highly sought-after timepiece within the Royal Oak lineage. Its stainless steel 39mm case maintains the iconic octagonal bezel with visible screws, an unmistakable signature of the Royal Oak’s bold design. The dark grey “Tapisserie” dial is enhanced by three subdials for chronograph functions and a date aperture positioned at 4 o’clock, balancing elegance with practicality. This watch is driven by the Caliber 2385 automatic movement, delivering precision and reliability, along with a 40-hour power reserve. Completing the design is the integrated stainless steel bracelet with a folding clasp, ensuring both durability and a seamless fit. This full set, including its original box and papers, is a prime acquisition for collectors who appreciate Audemars Piguet’s legendary craftsmanship.
