The ProPilot X Caliber 400 automatic watch is the latest in a long line of Oris watches for pilots dating back to the early 1900s. In addition to being a classic timepiece instrument, this watch has a unique quality: it is a mechanical instrument capable of giving joy.

The ProPilot X Caliber 400 is powered by a new generation, high performance automatic mechanical movement being designed directly by qualified engineers. The movements of the Caliber 400 Series differ in their high levels of anti-magnetism, a 5-day power reserve and a 10-year warranty. These models are defined by Oris as the "new standard".
