Description

The 41mm yellow gold construction of this Royal Oak Selfwinding Chronograph delivers commanding wrist presence while maintaining the refined proportions that made the octagonal case legendary. This “Matthew Williams” edition, reference 26240BA.OO.1320BA.01, represents the intersection of Audemars Piguet’s haute horlogerie heritage with the avant-garde vision of the ALYX founder and Givenchy creative director. Williams transformed the iconic Royal Oak design language through his streetwear-influenced lens, creating a timepiece that speaks to collectors who appreciate both mechanical excellence and contemporary cultural relevance. The yellow gold bracelet with integrated AP folding clasp ensures this collaborative masterpiece sits securely on the wrist with the substantial feel expected from Le Brassus.
