The first watch powered by the groundbreaking Oris Calibre 400

The Oris Aquis Date Calibre 400 is a high-performance diver’s watch with a stainless steel case and bracelet (now with Oris’s new Quick Strap Change system), 30 bar (300 metres) of water resistance and a uni-directional rotating bezel with a ceramic insert.

The movement

Calibre 400 is an entirely new movement, independently conceived by Oris for the world citizen, and sets the new standard for automatic mechanical movements by being highly accurate and highly reliable. 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. This is 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.

A modern watch

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.

Calibre 400: a current movement

Many of us now own more than one watch. Sometimes we might wear a smartwatch. We also expect a luxury watch to last, partly because it’s a considered purchase, but also because we’re more conscious of the impact our choices have on our planet. A successful contemporary calibre will accommodate all this and reflect the way we live and the world we live in. Having agreed on the philosophy behind the movement, we then faced the higher challenge of actually creating it. Building a movement from the ground up is more than simply creating a list of functions; you also have to deliver a dependable, reliable mechanism that will perform accurately between recommended service intervals. The challenge is to create a movement that works in the real world. That is what Calibre 400 delivers.

The Aquis Date watch

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 Aquis 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 in the new watch, 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 our milestone movement is as open as it can be.

At the same time, the watch remains water-resistant to 30 bar (300 metres) and still has a unidirectional rotating bezel with a scratch proof ceramic insert for safely timing dives, as well as SuperLumiNova® hands and indices.
