Introducing the Aquis Pro 4000m, the most advanced diver’s watch we’ve ever created. The 49.50 mm titanium watch’s headline feature is its 400-bar (4,000-metre) water resistance rating, deeper than Oris has ever gone before. The Aquis Pro 4000m is a high-tech watch with extreme water resistance. Its key feature is the Oris-patented Rotation Safety System (RSS), designed with divers to lock the bezel, preventing accidental adjustments during a dive. It also has a secure folding clasp and a screw-down crown.
