Oris is delighted to introduce the Aquis Pro 4000m, the most water resistant divers watch Oris have ever created with a titanium case that can withstand pressures up to 400 bar (equivalent to 4, 000 metres depth). Its 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 Oris security folding clasp extension system, which means the strap can be easily adjusted for length while the watch is being worn. Its also powered by Oris Calib re 400, our 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 My Oris. Its finished with a blue gradient dial decorated with a wave pattern, a blue ceramic bezel insert with a minutes scale for timing dives, and a blue rubber strap.
