The AquisPro 4000m, the most water-resistant diver’s watch Oris has ever created with a titanium case that can withstand pressures up to 400 bar (equivalent to 4,000 metres depth). It’s 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 security folding clasp extension system, which means the strap can be easily adjusted for length while the watch is being worn.
