Introducing the Audemars Piguet Royal Oak Selfwinding Chronograph 26240OR.OO.1320OR.08. The 41mm case is made of 18k rose gold and complements the Grande Tapisserie dial in khaki green. Luminescent rose gold hand and hour markers work with the Sapphire glare-proofed crystal for optimal legibility in any condition. An exhibition case back gives a glimpse at the Calibre 4401 in action, powering all of the watch's complications, including Flyback chronograph timekeeping and date features.
