The Oris Dat Watt Limited Edition II REF 01 743 7734 4197-Set is a special tribute to the UNESCO World Heritage Wadden Sea and its vital salt marsh ecosystem. Limited to 2,009 pieces—commemorating the year the Wadden Sea was awarded World Heritage status—this 43.5 mm dive watch blends ecological significance with robust functionality.

The stainless steel case features a unidirectional rotating bezel with a grey tungsten insert, a screw-down crown with protection, and a domed sapphire crystal with anti-reflective coating inside for superior legibility underwater. The shimmering green dial is inspired by the salt marshes of the Wadden Sea and equipped with hands and indices filled with Super-LumiNova®.

Powered by the Swiss Made automatic Oris Calibre 743, the watch offers a small seconds subdial at 9 o’clock, a circular date indicator, and a 38-hour power reserve. Water resistant to 30 bar (300 meters), it comes with both a three-link stainless steel bracelet and a blue rubber strap, each with a safety folding clasp featuring an extension system for comfortable wear over a wetsuit.

The Dat Watt Limited Edition II symbolizes Oris’ commitment to environmental conservation and Change for the Better, continuing its partnership with the Common Wadden Sea Secretariat to protect this unique ecosystem for future generations.
