Oris 774

Caliber 774 is an automatic chronograph movement manufactured by Oris, based on the Sellita SW500. Operating at 28,800 vph, it delivers a 48-hour power reserve and contains 25 jewels. As a non-in-house movement, it represents Oris's use of reliable Swiss ébauches for its chronograph collections. The caliber remains in production and serves as the base for several Oris chronograph models.
