The Royal Oak is widely recognised as one of the most iconic wristwatches designs ever created. Since its debut in 1972, this legendary sport-chic timepiece has spawned numerous variations, including an elegant chronograph model like the one presented here. Introduced in 1998 as the Royal Oak Chronograph under the reference 25860ST, this watch offered a range of dial colors and was available in precious metals. The present model showcases a visually appealing dark blue dial, featuring the distinctive Tapisserie pattern that has been synonymous with the Royal Oak since its inception. Powered by an F. Piguet-based movement, this chronograph incorporates both a date function and sporty features, enhancing its practicality and versatility. Notably, this reference gained widespread recognition when renowned chess Grandmaster Garry Kasparov proudly wore it🅠 during his professional matches, leading to its affectionate nickname "Kasparov" among collectors who appreciate its symbolic connection to the strategic brilliance of the game.
