Swiss watch brand Oris introduces a special edition diving timepiece 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. Based on the Oris Aquis diver’s watch, the Dat Watt Limited Edition is named after a local dialect for the Wadden Sea.
Known for their contributions for conserving the nature, Oris has been working with non-profit environmental organisations and clean-up movements all over the world. The latest project is with the Common Wadden Sea Secretariat (CWSS), a tri-lateral organisation covering Denmark, Germany and the Netherlands that works to conserve and protect the Wadden Sea, the world’s largest unbroken tidal flat system. In 2009, UNESCO awarded it World Heritage Site status to reflect its importance to global biodiversity.
The Wadden Sea is the largest unbroken tidal flat and barrier-island depositional system in the world. Covering 11,500km2 in the North Sea, it is largely flat and hugely bio-diverse. At any one time, there are more than 6 million birds inside its borders. Each year, between 10 and 12 million migratory birds pass through it. The salt marshes host around 2,300 species of flora and fauna, and there are a further 2,700 species in the marine and brackish areas, and more than 30 species of breeding birds.
The Wadden Sea covers an area of 11,500km2, has a 500km coastline and is a vital stopping point for more than 10 million migratory birds every year. This makes it one of the most important natural properties on the planet. In fact, experts have calculated that biodiversity on a worldwide scale is reliant on the Wadden Sea.
To this point, it’s also remarkable because it’s one of the few remaining natural large scale intertidal ecosystems where natural processes continue to function largely undisturbed. This is why it needs protecting. As with so many marine environments, the Wadden Sea is under constant threat from fishing, harbour development, oil and gas rigs, wind farms, maritime traffic, residential and tourism development, and the impact of climate change. This is the role of the Common Wadden Sea Secretariat, acting on behalf of the Trilateral Wadden Sea Cooperation. Its executive secretary is Bernard Baerends.
This organization is funded on an equal one-third basis by the three nature and environment ministries of Denmark, Germany and the Netherlands. Its partnership with Oris is the first with a private company outside the Wadden Sea area. This relationship set to run for a minimum of three years. It begins with the specially developed Dat Watt Limited Edition – Dat Watt means ‘the Wadden Sea’ in Low German.
The Dat Watt Limited Edition is a special diving timepiece based on the brand’s popular Aquis family of diving watches.
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.
Featuring a 43.50mm diameter case in stainless steel, the watch has a water resistance of 300 meters. This 2,009 piece limited edition marks the year the Wadden Sea was awarded UNESCO World Heritage Site status.
