Details & Specifications

Introducing the Dat Watt Limited Edition II

We’re delighted to announce that we’ve extended our collaboration with the Common Wadden Sea Secretariat to the end of 2025, and to present the Dat Watt Limited Edition II, a watch based on our Aquis diver’s watch that supports the conservation of one of the world’s most vital ecosystems.

Limited to 2009 Pieces Worldwide. 

Salt and light

The watch has a unique green dial, coloured to reflect the way light reflects off the salt marshes found in the Wadden Sea, an area that covers 11,500 km2 in northern Europe. The watch also features an unusual circular date indication, driven by a Swiss made automatic mechanical movement. It’s water-resistant to 30 bar (300 metres) and comes with both a bracelet and an interchangeable rubber strap. Only 2,009 pieces will be made, marking the year the Wadden Sea was listed as a UNESCO World Heritage Site.
