Yangtze Jiangtun Limited Edition

Dubai, UAE, January 2026: Oris is proud to unveil the Yangtze Jiangtun Limited Edition, a purpose driven timepiece created in partnership with the Changjiang Conservation Foundation to support the protection of the critically endangered Yangtze finless porpoise. This release embodies Oris’s enduring dedication to both the planet and the art of Swiss watchmaking.
The Yangtze finless porpoise, locally known as Jiangtun, is the last remaining freshwater cetacean in China and a treasured species of the Yangtze River ecosystem. Found only in the Yangtze River, it has faced severe population decline due to habitat loss, pollution, and human activity. In partnership with the Changjiang Conservation Foundation, Oris shines a light on the species and supports the foundation’s efforts to protect the river’s biodiversity through research, public awareness, and community led initiatives. In 2022, surveys estimated that just 1,249 individuals remain in the wild, highlighting the fragile beauty of this rare species.

Based on the Aquis Date 43.50 mm, the Yangtze Jiangtun Limited Edition translates this conservation mission into thoughtful design details. The blue-green mother-of-pearl dial captures and reflects light like the surface of the Yangtze River, enhanced by a wave pattern applied using a precise printing process inspired by the ultrasonic clicks the finless porpoise uses to communicate and navigate its cloudy waters. Crafted in stainless steel, the watch is powered by the Oris Calibre 733 automatic movement and designed for performance, with water resistance to 30 bar (300 metres). On the reverse, the case back is engraved with an image of the porpoise, reinforcing the emotional link between the timepiece and the species it represents.
 
The Yangtze Jiangtun Limited Edition is limited to 1,249 pieces, representing the number of the aquatic mammal thought to be left in existence. Through this release, Oris and the Changjiang Conservation Foundation aim to support ongoing conservation efforts, underscoring a shared belief that while no single individual can change the world alone, collective action can help protect it for the future.
