The watch features a 43.5 mm multi-piece stainless steel case with a unidirectional rotating bezel. Its luminous aqua green mother-of-pearl dial shimmers with a subtle oyster-shell effect. A domed sapphire crystal with anti-reflective coating enhances the dial’s depth, while hands and indices filled with Super-LumiNova® ensure clear readability. The watch comes with a stainless-steel bracelet and an additional aqua green rubber strap, offering both elegance and versatility. Engineered for 300 meters of water resistance, this 2,000-piece numbered edition retails for CHF 2,550.

Proceeds will support reef building, shell recycling, and educational programs that engage thousands of students and volunteers. Since 2014, the Billion Oyster Project has restored over 150 million oysters to New York Harbor, creating vital habitats and fostering environmental stewardship.

Oris Co-CEO, Rolf Studer, says, “The ecological challenge can feel overwhelming, but when we work together, it gets easier. We’re proud to collaborate again with Billion Oyster Project and witness first-hand the change we’re bringing together.”
