Oris is one of a small handful of Swiss watch brands that only manufacture mechanical watches.

A mechanical watch is a magnificent piece, designed according to principles that have existed for generations and will continue to exist long into the future.

Oris constantly strives to manufacture better watches that offer beautiful innovative features and advanced performance levels. For example, the Calibre 400 series of Swiss-made automatic watches developed in-house promises a five-day power reserve, anti-magnetic properties, a 10-year warranty, and recommended service intervals of 10 years.
