The new standard
Calibre 400 is an entirely new movement, independently conceived by Oris, and sets the new standard for automatic mechanical movements. It has a five-day power reserve (120 hours), is highly resistant to magnetism, and comes with 10-year recommended service intervals and a 10-year warranty.Five-day power reserve
When conceptualising Calibre 400, Oris’s engineers recognised that these days we may not wear the same watch every day. If you put a standard mechanical watch down for a day or two, it will stop as the power reserve runs down. Calibre 400 has a five-day power reserve, so it’ll still be running if you’ve not worn your watch between, say, Thursday and Tuesday. It delivers this longer period of use via twin barrels, both of which house an extended mainspring, each long enough to store two-and-a-half days of power.10-year warranty and recommended service intervals
Oris is so confident in the performance of the advanced technologies integrated into Calibre 400 that we are offering a 10-year warranty on all Oris watches powered by the new movement when you register them at MyOris. In addition, Oris is also proposing 10-year recommended service intervals on Calibre 400 watches. This means that barring accidental damage or water resistance checks, you shouldn’t need to bring in a Calibre 400 watch for a service until 2030 at the earliest. This is the new standard.A more stable rotor system
One of Oris’s fundamental ambitions with Calibre 400 was to eliminate problems before they occur.
