The Audemars Piguet Royal Oak Chronograph represents the latest evolution of one of the most iconic luxury sports watches ever created. Housed in a 41mm stainless steel case, this model features the legendary octagonal bezel secured by eight white gold hexagonal screws and the signature integrated Royal Oak bracelet. The dial is finished with Audemars Piguet's distinctive "Grande Tapisserie" pattern, offering depth, texture, and exceptional legibility. At its heart is the in-house Calibre 4401, a selfwinding flyback chronograph movement visible through the sapphire caseback, delivering a 70-hour power reserve and showcasing AP's modern technical craftsmanship. Blending heritage design with contemporary engineering, the 26240ST is a true grail piece for collectors seeking a refined yet sporty chronograph with timeless appeal.
