Oris 764

Oris caliber 764 is an automatic movement introduced in 2016 and based on the Sellita SW220-1. Running at 28,800 vph, it incorporates a moonphase complication that displays the lunar cycle. The movement is not manufactured in-house by Oris but relies on the established Sellita base. It remains in production and is used in various Oris moonphase watches.
