Looking to try servicing an old movement

Well I just found out that 90% of the designs I like have the numbers painted with radium paint, so I think that's ebay fever cured

There is a narrow section of time where tritium replaced radium as a lume, and it is much less of a theoretical health concern. Benrus tritium watches have a small “T” visible above the 12 on the dial, and other makes may have “T Swiss T” at the bottom of the dial. Although these are from the 60’s and newer, there are still some with vintage styling and parts are often more available than older movements.

Thanks! I wondered what the "T Swiss T" meant.

On the subject of parts, if a watch "winds & runs", what are the chances of it "just" needing a clean and a service if it's from 40s, 50s, 60s? Just want to know what I'm potentially signing myself up to.
