The Oris Yangtze Jiangtun Limited Edition automatic watch is a high-performance timepiece born from an extraordinary mission: the protection of the Yangtze finless porpoise. Created in collaboration with the Changjiang Conservation Foundation (CCF), this watch is not only a masterpiece of Swiss mechanics but a tangible commitment to safeguarding a critically endangered species.

The aesthetic heart of this limited edition is its blue-green mother-of-pearl dial. The choice of material captures the reflections of the Yangtze River’s surface, while a refined wave pattern graphically reproduces the ultrasonic pulses used by the finless porpoise for navigation and communication.

Based on the renowned 43.50 mm Aquis Date model, the Yangtze Jiangtun combines elegance with professional robustness:
Oris Calibre 733 automatic mechanical movement with a 41-hour power reserve
Stainless steel case and unidirectional rotating bezel with a scratch-resistant tungsten insert
Water-resistant to 30 bar (300 meters), ideal for any underwater exploration
Super-LumiNova® hands and indices for perfect legibility in all lighting conditions

This timepiece is limited to just 1,249 pieces worldwide. The number is not symbolic: it pays tribute to the last remaining finless porpoises recorded in the wild. The steel case back is embellished with a special engraving depicting the cetacean and features the unique edition number.

By purchasing the Oris Yangtze Jiangtun, you directly support the CCF in its efforts to protect the Yangtze ecosystem.
