The deepest-diving Oris ever made

Diving deeper than ever before, the Oris AquisPro 4000m expands on the maker's professional diving series with a buryly new titanium case built to withstand pressures up to 400 bar (equivalent to 4,000 meters, or 13,100 feet), four times the depth of the standard AquisPro. This watch is also loaded with Oris-patented technology, including the Rotation Safety System bezel, designed by Oris in collaboration with professional divers to lock the bezel in place, and the brand's own security folding clasp extension system, which means the strap can be easily adjusted for length while the watch is being worn.

It’s also powered by Oris Calibre 400, a high-performance automatic mechanical movement, which offers a five-day power reserve, elevated anti-magnetism, better than chronometer accuracy and 10-year recommended service intervals and a 10-year warranty with registration to MyOris. It’s finished with a blue gradient dial decorated with a textured wave pattern, a blue ceramic bezel insert with a minutes scale for timing dives, and a bright blue rubber strap. It is, without question the most capable dive watch Oris has ever built.
