Power play

The first watch to carry Oris’s gamechanging automatic movement is the Oris Aquis Date Calibre 400. Robust, stylish and high-tech, it’s a force to be reckoned with.

Oris’s current collection is full of high-performance, fit-for-purpose mechanical watches. But when it came to choosing which model should carry our groundbreaking new Calibre 400, there was only one candidate. The Oris Aquis Date.

Around the world, the Aquis is recognised as an icon of contemporary diver’s watch design. Strong, reliable, versatile and equipped with a long list of functions, it is chosen by men and women from all walks of life who love watches.

The new Aquis Date, powered by Calibre 400, has a number of differences to the standard model. The first clue to what lies beneath are the words ‘5 days’ written on the gradient blue dial. The date window is also larger and the date disc is black, rather than white. On the reverse, the sapphire case back is the largest we’ve ever installed in an Aquis Date, so the view into the movement is as open as it can be.

At the same time, the watch is still water-resistant to 30 bar (300 metres), has a uni-directional rotating bezel with a scratchproof ceramic insert for safely timing dives, and SuperLumiNova® hands and indicies.

It’s also equipped with Oris’s newest patented development, the Quick Strap Change system, engineered so a bracelet or strap can be released simply by lifting a flap. No tools required. No jeweller required.

In short, the Oris Aquis Date Calibre 400 sets the new standard in diver’s watches.

About the Movement.

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.

Moreover, because it’s an Oris calibre, every detail has been scrutinised to ensure the highest possible quality at the best possible price. That has always been the Oris movement creation philosophy.

Oris Calibre 400 was conceived five years ago. The ambition, which was born years before, was to produce not just a highly accurate automatic movement, but one that would serve today’s world citizen.

Modern life is more demanding of a mechanical watch than it was. We’re now surrounded by magnetic fields that can have an adverse effect on a watch movement – magnets are in computers, phone cases, air bags… and because of advances
in manufacturing, it’s expected that a mechanical watch will perform better and for longer than ever before.

Caliber 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, high levels of anti- magnetism, and comes with 10-year warranty and 10-year recommended service intervals. Here’s how it works.

1) Twin barrel concept

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.

2) Class-leading reliability

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 water- resistance 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.

3) Invention at its core

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.

4) Highly anti-magnetic

Most Swiss watch movements will be magnetized 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 anti- magnetic, 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.
