39mm titanium case, in-house manufactured Calibre 400 movement, blue dial, multi-piece titanium bracelet.

The joy of mechanics comes to the fore in the new ProPilot X Calibre 400, a titanium-cased watch inspired by more than a century of aviation heritage and powered by our five-day automatic.

Mechanical joy machine

The ProPilot X Calibre 400 follows in a long line of Oris pilot’s watches going back to the early 1900s, but its power lies beyond its associations: it’s a mechanical joy machine.

Calibre 400

Inside the ProPilot X Calibre 400 is one of our new generation of high-performance automatics. Conceived entirely in-house by our skilled engineers, Calibre 400 Series movements all feature elevated levels of anti-magnetism, a five-day power reserve and a 10-year warranty. We call this The New Standard.
