The Oris Great Barrier Reef Limited Edition IV REF 01 400 7790 4185-Set is a 43.5 mm stainless steel dive watch inspired by Oris’s long-standing partnership with the Reef Restoration Foundation, dedicated to protecting the world’s largest coral reef system. Limited to 2,000 pieces, it features a stunning gradient blue dial housed in a multi-piece stainless steel case with a tungsten minutes scale top ring.
At its heart beats the Oris Calibre 400, a high-performance automatic movement offering a five-day power reserve, enhanced anti-magnetism, and backed by a 10-year warranty with recommended 10-year service intervals. The watch combines professional dive functionality with a strong environmental commitment.
Water resistant up to 30 bar (300 meters), the case includes a domed sapphire crystal with anti-reflective coating on the inside and a screwed stainless steel case back engraved with special motifs. The dial shows hours, minutes, seconds, and an instantaneous date with a corrector function, offering clarity and precision for every dive.
This limited edition stands as a tribute to the resilience of the Great Barrier Reef and reflects Oris’s ongoing dedication to sustainability and marine conservation.
