Indeed, the Calibre 400 is sized to sit in for the third-party movements that power many models.

This is confirmed by the fact that Oris put the Calibre 400 into their best selling watch, the Aquis, and not into a more esoteric and expensive watch like the Pro Pilot X which houses Oris’ previous in-house release. In fact, the Calibre 400 isn’t Oris’ first in-house movement in recent history, but it is the first one that appears destined to serve in a variety of Oris’ watch models.

Typical of Oris, their approach to making an in-house movement was to offer better value and quality to their customers, not to up their brand’s profile as une manufacture. Designed from the ground up over five years, the Calibre 400 has a number of thoughtful features that add up to a 10-year service interval and warranty, robust a-magnetism and accuracy, and a 5-day power reserve. Oris’ CEO VJ Geronimo recently came on a recent episode of the podcast to talk about a new in-house movement, the Calibre 400.
