Oris introduces a watch created with the Common Wadden Sea Secretariat and its mission to conserve the Wadden Sea, the world’s largest tidal system and a UNESCO World Heritage Site. Like nature, Oris’s Change for the Better campaign is unlimited by treaties or border controls. It’s also holistic. Change for the Better is about conserving our planet, just as it’s about improving people’s lives. At Oris, we take this responsibility extremely seriously, which is why we’re on a mission to bring Change for Better. As well as entering into partnerships with conservation agencies and supporting projects designed to clean up the world’s water sources, we’re also on a sustainability drive here in Hölstein. Based on the Oris Aquis diver’s watch, the Dat Watt Limited Edition is named after a local dialect for the Wadden Sea. The 2, 009 pieces mark the year the Wadden Sea was awarded UNESCO World Heritage Site status. The Dat Watt Limited Edition is a special watch. Its dial displays the lunar cycle and tidal range in the Northern Hemisphere via the Oris-developed Pointer Moon function, created for professional divers. This works using a central white pointer hand that once aligned with the correct day in the 29. 5-day lunar cycle, shows the corresponding tidal range via the white outline on the dial. The same hand indicates the waxing and waning of the moon.
