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.

Inside the ProPilot X Calibre 400 is one of the manufacture's new generation of high-performance automatics. Conceived entirely in-house by the company's skilled engineers, Calibre 400 Series movements all feature elevated levels of anti-magnetism, a five-day power reserve and a 10-year warranty.
