Founded in 1904 in the Swiss village of Hölstein near Basel, Oris is known for producing some of the world’s most practical mechanical timepieces. An Oris watch embodies the values of the Swiss art of watchmaking, with fascinating micro-mechanical components and distinctly stylish exteriors. The independent company is one of the few Swiss watch brands that manufacture only mechanical watches, some of which are co-developed by well-known professionals from the worlds of diving and aviation. Classic complications committed to heritage and innovation complement the offering.
Driven by the ambition to produce a highly accurate automatic movement that lives up to highest expectations, Oris developed the Calibre 400. With a five-day power reserve, increased resistance to magnetism and a rotor system with increased stability, it sets a new standard for automatic mechanical movements. It comes with a ten-year warranty, and a ten-year recommended service interval.
