Created with purpose, the Oris Aquis Date Yangtze Jiangtun Limited Edition, model number 01 733 7789 4197-Set, pairs thoughtful design with meaningful intent. Housed in a 43.5mm multi-piece stainless steel case, this distinctive diver is defined by its lustrous mother-of-pearl dial, each surface catching the light with soft, natural variation. The tungsten minutes scale top ring adds reassuring weight and durability, while the domed sapphire crystal with internal anti-reflective coating offers clarity and a refined tactile finish. A screwed stainless steel case back features special engravings that mark its limited status and story.

Limited to just 1,249 pieces, this edition supports the Changjiang Conservation Foundation and the protection of the critically endangered Yangtze finless porpoise. With 30 bar (300 metres) of water resistance, it remains true to the Aquis Date’s professional diving credentials, yet its elegant materials make it equally suited to everyday wear. A considered choice for collectors and those who value craftsmanship with conscience, this is a modern sports watch with enduring relevance.
