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.


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

I’ll say it in English then: this is the first in-house calibre that ia overpriced by 50% at the least. C’mon friends of the horology, let’s face it … $2000 for an Oris Aquis with the Sellita SW200 and now $3500 for the only difference of a caliber 400 (&401) ?!! Getvreal, even the STP movements could do the same job. Cal. 400 of Oris is heavily overpriced.

You’re so right on this, Frenchie. Love you for sayingbit straight on. This is a real big hoax, this more than 50% overpricing of this Swiss haughty company of snobs with their Cal.400, yuck!

Whats the point of your comment? Afraid that 120+hrs powerreserve obsoletes your highly appreciated ordinary toy?

My opinion is that this is a pretty stupid comment. That’s like comparing plums to apples and calling fruit like fruit. – could do the same job
Power Reserve 38 hours vs. 120
warranties 2y vs. 10y
3 party vs. inhouse development
