Oris 751

The Oris Calibre 751 is an automatic movement based on the Sellita SW220-1, featuring a day-date complication. Operating at 28,800 vph, it was introduced in 2010 and remains in production. As a non-in-house caliber derived from a established Swiss ébauches, it represents Oris's use of reliable modified base movements to populate its entry-level and mid-range collections.
