41.5mm stainless steel case, automatic in-house Calibre 400 movement with date function, green dial. 

Created by Oris for today's world citizen, the Oris Calibre 400 sets the new standard with an anti-magnetic automatic movement, a five-day power reserve and a 10-year warranty. This new movement was conceived entirely in-house and uses a twin barrel concept and more than 30 non-ferrous and anti-magnetic components to meet the demands of our modern life.

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. 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 anti-magnetism and a five-day power reserve, and comes with a 10-year warranty and 10-year recommended service intervals.
