Oris Divers Carl Brashear Calibre 401 Automatic 40mm Limited Edition

Oris introduces the third watch made in partnership with the Carl Brashear Foundation and the first powered by Oris’s in-house Calibre 401, a highly resistant five-day automatic. Most Swiss watch movements will be magnetised if exposed to the strong magnetic forces we encounter in daily life. When this happens, they become less accurate, and can stop altogether. To make them highly anti-magnetic, Oris engineered movements in the Calibre 400 Series using more than 30 non-ferrous and anti-magnetic components, including a silicon escape wheel and a silicon anchor. In testing by the renowned Laboratoire Dubois, Calibre 401 deviated by less than 10 seconds a day after exposure to 2,250 gauss. For many reasons, you may not wear a mechanical 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 401 has a five-day power reserve so it’s ready to go when you are. It delivers this longer period of use via twin barrels
