Oris returns to the Great Barrier Reef with a third limited edition watch, this time introduced as part of the independent Swiss watch company's new series, The Oceans Project, aimed at raising awareness of the many threats to the health of the world's oceans. The new watch, which is based on Oris's high-performance Aquis diver's watch, will directly support the coral planting activities of Reef Restoration Foundation, an Australian non-profit. It features a gradient blue dial, a blue ceramic bezel insert and a novel circular date window.
