·This 63 looks to be without bevel. https://omegaforums.net/threads/omega-speedmaster-105-003-63-with-extract-and-fresh-service.90157/
I think the 63 has the same decorated/undecorated inner case back also.
Agree, that does look like a typical, non-bevel '64 case...rather than a beveled one, that has been re-finished. However, and I will admit straight away that this is over my pay-grade (no MWO), the extract shows a date of production that is a month away from 1966. Don't know where the serial number fits in. A late '63 with one of the newer case-makers cases?
Edit: checked Speedmaster 101; 22824X does appear as starting 1965 production, so last of the '64 cases, with an earlier back?
