The joy of mechanics

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 case back, it warms us to see how things work. At Oris, we’re driven by this joy. Because if there’s one thing our watches have to do, it’s bring a smile. We know no one needs a mechanical watch. But the simple pleasure of owning one and seeing it work makes life that much more enjoyable. That’s what we mean by the joy of mechanics.

Calibre 400

Oris Calibre 400 Series sets the new standard in automatic mechanical watchmaking. Conceived entirely in-house by the independent Swiss watch company’s skilled engineers, it offers elevated levels of antimagnetism and a five-day power reserve, and comes with a 10-year warranty and 10-year recommended service intervals.
