Looking at a Tudor 7017/0 circa 1970. It has a DAY-DATE dial with SWISS MADE text and roman numbers. Most other 7017 from that era has the DATE+DAY dial with T SWISS T or just SWISS and I have not seen anyone with the roman numbers when searching online.
Am I looking at some kind of service dial or was there different versions available?

Thanks for any input from all you Tudor experts out there.
