Oris’s engineers developed Calibre 400 to meet the demands of today’s watch wearer. It makes three key performance promises:
  • A 10-year warranty: A modern luxury watch should be reliable. Any Oris watch carrying Calibre 400 is guaranteed for 10 years when you register it at MyOris.
  • Five-day power reserve: For many reasons, you may not wear a mechanical watch every day. Calibre 400 has a five-day power reserve so it’s ready to go when you are.
  • Anti-magnetic: Calibre 400 has more than 30 anti-magnetic components and exceeds the norms required by the ISO 764 enhanced anti-magnetic standard.
