A watch born to make a difference.

The Oris Yangtze Jiangtun Limited Edition celebrates the Swiss brand’s concrete commitment to environmental protection by supporting the Changjiang Conservation Foundation in protecting the Yangtze finless porpoise, one of the rarest and most endangered species in the world.

Based on the iconic 43.50 mm Aquis Date , this timepiece combines professional performance and strong symbolic value. The stainless steel case , unidirectional rotating bezel with tungsten insert , screw-lock crown , and water resistance to 300 meters make it a true Swiss Made diver's watch, reliable in any conditions.

The green-blue mother-of-pearl dial , embellished with a wave pattern inspired by the finless porpoise's ultrasound, captures the light like the surface of the Yangtze River. On the engraved caseback, the finless porpoise and the individual numbering recall the importance of each individual specimen: a limited edition of 1,249 pieces , like the number of individuals remaining in the wild.

Inside beats the Oris Calibre 733 automatic movement , with 41 hours of power reserve , a guarantee of precision and reliability over time.

Choosing this watch means wearing a fine watchmaking timepiece and contributing to a real cause.
Because no one can change the world alone, but everyone can do their part.
