The Oris caliber 401 is an automatic watch movement with a small seconds subdial at 6:00. This Swiss made caliber has 24 jewels. The 401 was officially announced in September, 2019.

Some of the topics covered in this caliber listing:

Power Reserve:

The Oris 401 is equipped with two sets of components that extend its power reserve ability beyond a standard automatic watch movement: Twin barrels and extended length mainsprings. Each spring and barrel configuration can store up to 2.5 days of energy for a total of five days on a full wind.

Accuracy:

Oris claims that the caliber 401 has an average accuracy rating of -3/+5 seconds per day. In addition to these performance claims, Oris has designed the 401 to be resistant to magnetism thanks to “more than 30 non-ferrous and anti-magnetic components, including a silicon escape wheel and a silicon anchor.” This helps to maintain the accuracy of the watch even when exposed to magnetic fields. As Oris puts it:

“In testing by the renowned Laboratoire Dubois, Calibre 401 deviated by less than 10 seconds a day after exposure to 2,250 gauss.” –source
