This 41 mm Royal Oak Selfwinding Chronograph, entirely crafted from black ceramic and accented with refined rose gold details, features the collection’s latest design evolution and a special "50-years" anniversary oscillating weight. 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 chronograph timekeeping and date features.
