One of the reasons Oris is best known for is its dive watches which come from its popular Divers Sixty-Five line up. However, it is the professional dive watches where Oris utilizes its technical know how to create watches that can go to the depths of 1000m and continue keeping time accurately. Introducing the Oris Aquis Pro Date Cal 400. This is Oris’s first professional divers watch equipped with Oris’s in house Calibre 400 movement. The Aquis Pro Date is a natural home for Oris’s high-performance Calibre 400. Designed to serve professional divers on saturation dives, it is a highly technical tool watch chosen by divers who work on complex engineering projects in helium-enriched environments hundreds of metres below the water’s surface.
The watch boasts elevated levels of anti-magnetism, superior accuracy compared to a chronometer, a five-day power reserve and a 10-year guarantee, Calibre 400 is the new standard in Swiss Made automatic mechanical movements.
Among its special features is Oris’s patented Rotation Safety System, known as RSS. This exclusive Oris device, commissioned by the professional diving community, enables the wearer to adjust and lock the uni-directional rotating bezel into place. This means that during a dive they can read off remaining dive time with absolute certainty.
The watch case is made with high-grade, light-weight titanium and has low-glare black DLC (Diamond-Like Carbon) coating. This makes the 49.50mm case extremely comfortable on the write. Titanium is also used for the rubber strap’s folding clasp, where you’ll find two more exclusive Oris innovations. The patented Oris Sliding Sledge Clasp can be adjusted to very fine tolerances without taking the watch off, so that when getting in or out of even the thickest wetsuit, you can loosen or tighten the strap hassle-free. The rubber strap also features the Oris Safety Anchor, developed by Oris so that in the event the clasp is released unintentionally, two hooks grab the strap so the watch stays attached to the wearer’s wrist. Innovations such as these have made the AquisPro a long-standing favourite with professional divers.
Oris has set a new benchmark with its Calibre 400 movement. Most importantly provides features of high end mechanical movements at an affordable price point. The Calibre 400 has 5 day power reserve, elevated levels of anti-magnetism, and comes with a 10-year warranty and 10-year recommended service intervals. It delivers this longer period of use via twin barrels, both of which house an extended mainspring, each long enough to store two-and-a-half days of power.
Oris is so confident in the performance of the advanced technologies integrated into Calibre 400 that we are offering a 10-year warranty on all Oris watches powered by the new movement once registered with MyOris. In addition, Oris is also proposing 10-year recommended service intervals on Calibre 400 watches. This means that barring accidental damage or water-resistance checks, a Calibre 400 watch won’t need servicing until 2030 at the earliest. This is The New Standard.
The Calibre 400 movement consists of 30 non-ferrous and anti-magnetic components, including a silicon escape wheel and a silicon anchor. In testing by the renowned Laboratoire Dubois, Calibre 400 deviated by less than 10 seconds a day after exposure to 2,250 gauss. As per the ISO 764 standard, an anti-magnetic watch must be accurate to within 30 seconds a day after exposure to 200 gauss. Oris has statistically gone above and beyond and created a highly functional tool watch.
