Natural home for Oris’s high-performance Calibre 400
The AquisPro Date is a natural home for Oris’s high-performance Calibre 400. Designed to serve professional divers on saturation dives, it’s 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. 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. A chunky rubber grip makes it easy to operate, even when gloved, while a yellow and white minutes scale engraved into the scratch-resistant ceramic bezel insert delivers high levels of low-light legibility.Calibre 400
Oris Calibre 400 sets The New Standard in mechanical watchmaking. Conceived entirely in-house by the independent Swiss watch company’s skilled engineers, it has a five-day power reserve, elevated levels of anti-magnetism, and comes with a 10-year warranty and 10-year recommended service intervals.Natural home for Oris’s high-performance Calibre 400

A chunky rubber grip makes it easy to operate, even when gloved, while a yellow and white minutes scale engraved into the scratch-resistant ceramic bezel insert delivers high levels of low-light legibility.The new standard
Calibre 400 is an entirely new movement, independently conceived by Oris, and sets the new standard for automatic mechanical movements. It has a five-day power reserve (120 hours), is highly resistant to magnetism, and comes with 10-year recommended service intervals and a 10-year warranty.Five-day power reserve
When conceptualising Calibre 400, Oris’s engineers recognised that these days we may not wear the same watch every day. If you put a standard mechanical watch down for a day or two, it will stop as the power reserve runs down. Calibre 400 has a five-day power reserve, so it’ll still be running if you’ve not worn your watch between, say, Thursday and Tuesday. 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. It’s highly accurate, to -3/+5 seconds a day, better than a chronometer.10-year warranty and recommended service intervals
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 when you register them at MyOris. In addition, Oris is also proposing 10-year recommended service intervals on Calibre 400 watches. This means that barring accidental damage or waterresistance checks, you shouldn’t need to bring in a Calibre 400 watch for a service until 2030 at the earliest. This is the new standard.A more stable rotor system
One of Oris’s fundamental ambitions with Calibre 400 was to eliminate problems before they occur. Oris’s engineers identified that one of the most frequent issues with automatic mechanical movements concerns the ball-bearing system that allows the free-spinning oscillating weight (or rotor) to rotate. This is a critical element of an automatic watch – as the rotor spins, it generates power that’s stored in the mainspring, which is housed in the barrel. So we removed the ball bearing altogether and replaced it with a low-friction slide bearing system, in which a metal stud runs through a lubricated sleeve. This is much less complex, highly efficient, and involves far less wear and tear, making it less prone to breakdowns.Elevated resistance to magnetic fields
Most Swiss watch movements will be magnetised if exposed to the strong magnetic forces we encounter in daily life. When this happens, they become less accurate, and can stop altogether. To make it highly antimagnetic, Oris engineered Calibre 400 using more than 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. For context, the latest version of the ISO 764 standard for anti-magnetic watches requires that to qualify as anti-magnetic, a watch must be accurate to within 30 seconds a day after exposure to 200 gauss. Calibre 400 recorded one third of the deviation allowed after exposure to more than 11 times the force permitted, making it a highly anti-magnetic movement.- MOVEMENT Automatic winding date developed by Oris

Only it isn’t called a ProDiver these days; it’s called an AquisPro but needless to see this is the diver’s model that is aimed squarely at professional divers such as those working in the offshore industries and of course the desk diver among us that like their watches to have a bit of clout to them.
