Oris returns to the water with a 2,000-piece limited-edition created in support of the Australian non-profit Reef Restoration Foundation and our mission to bring Change for the Better.

Its stainless steel case, screw-in crown, crown protection, uni-directional rotating bezel and three-link bracelet have all been redesigned for improved ergonomics and performance. The watch features a especially engraved caseback featuring a Great Barrier Reef motif along with the limited edition number.
