The Yangtze Jiangtun Limited Edition is based on our best-selling Aquis Date 43.50 mm. That means it comes with all kinds of dive watch quality signifiers, including water resistance to 30 bar (300 metres), a uni-directional rotating bezel, a screw-down crown with protection, and lumed detailing for low-light legibility. And pointing to our collaboration with the Changjiang Conservation Foundation and its mission to save the Yangtze finless porpoise, it has a blue-green mother-of-pearl dial with an echo-sound-wave motif. #Oris #AquisDate #YangtzeJiangtun
