In our digital, connected, touch-sensitive world, the joy of mechanics has taken on new meaning. Whether we’re looking at a Ferris wheel with its open workings or a mechanical watch movement through a caseback, it warms us to see how things work. This is the joy that drives Oris. Because if there’s one thing the brand’s watches have to do, it’s make you smile. Oris knows that no one needs a mechanical watch. But the simple pleasure of owning one and seeing it work makes life that much more enjoyable.

This is why Oris only makes watches with mechanical movements. In the last eight years, that brand has conceived nine new calibers, constantly pushing the limits of mechanics to develop beautiful watch movements that make the mind wonder and the heart race.

The latest powers the Caliber 400 Series of automatic watches. Caliber 400 Series sets the new standard in Swiss Made automatics with elevated levels of anti-magnetism; five days of power reserve; accuracy superior to the chronometer standard (even after exposure to magnetism); 10-year recommended service intervals; and 10-year warranties on all Caliber 400 Series watches.
