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

Oris’s Calibre 400, designed for intermittent wear, has a five-day power reserve. It uses twin barrels with extended mainsprings, each storing two-and-a-half days of power. It’s highly accurate, to -3/+5 seconds a day, surpassing a chronometer.

10-year warranty and service

Oris’s Calibre 400, with its advanced technologies, offers a 10-year warranty on watches registered at MyOris. Oris also proposes 10-year service intervals on these watches, barring accidental damage or water-resistance checks. This sets a new standard.

A more stable rotor system

Aiming to pre-empt issues, Oris’s Calibre 400 addresses a common problem in automatic movements: the ball-bearing system. It’s replaced with a low-friction slide bearing system, simplifying the design, increasing efficiency, and reducing wear and tear.

High resistance to magnetism

Swiss watch movements can magnetise, affecting accuracy. Oris’s Calibre 400, engineered with over 30 non-ferrous, anti-magnetic components, is highly anti-magnetic. It deviated less than 10 seconds a day after exposure to 2,250 gauss, surpassing ISO 764 standards.
