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 engineers developed Calibre 400 to meet the demands of today’s watch wearer. It makes three key performance promises:

A 10-year warranty: A modern luxury watch should be reliable. Any Oris watch carrying Calibre 400 is guaranteed for 10 years when you register it at MyOris.

Five-day power reserve: For many reasons, you may not wear a mechanical watch every day. Calibre 400 has a five-day power reserve so it’s ready to go when you are.

Anti-magnetic: Calibre 400 has more than 30 anti-magnetic components and exceeds the norms required by the ISO 764 enhanced anti-magnetic standard.

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.
