The Audemars Piguet Royal Oak Selfwinding Chronograph 26240BA.OO.1320BA.01 is a distinctive collaboration with designer Matthew Williams of 1017 ALYX 9SM, crafted entirely in 18k yellow gold. Its 41mm case and integrated bracelet preserve the iconic Royal Oak design while introducing a modern, minimalist aesthetic.

Limited to 202 pieces, this timepiece blends high horology with fashion-led design, making it a highly collectible Royal Oak for those seeking exclusivity and a unique interpretation of the chronograph.
