Oris welcomes the AquisPro 4000m to its line-up

Delving deeper than ever before, the Swiss independent brand has introduced the most water-resistant diver’s watch in its collection, encased in titanium. True to its name, the AquisPro 4000m can withstand pressures up to 400 bar, equivalent to a remarkable depth of 4,000 meters.


ris has introduced the AquisPro 4000m, the most water-resistant diver’s watch it 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 its security folding clasp extension system, which means the strap can be easily adjusted for length while the watch is being worn.

The AquisPro 4000m is also powered by Oris Calibre 400, the brand’s 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 wave pattern, a blue ceramic bezel insert with a minutes scale for timing dives, and a blue rubber strap.
