I've put an inquiry in via Oris' website, but I thought I'd ask here as well in case anyone has already found this information.
I'm trying to find out what grade of Sellita movements Oris use in their watches, specifically the Aquis Date collection. The Oris caliber 733 is a base SW 200-1 with the branded red rotor, but Oris doesn't specify if the SW 200-1 is of Standard or Premium (Top) grade.
Using Top grade over Standard would mean an expected accuracy difference of +/- 12spd Vs 4spd, better shock protection, and improved isochronism:
Any info would be greatly appreciated!
