What to do?

For the dial, I'd say that you should do whatever will give you the most enjoyment. If you like it, leave it alone.

I really like the band. The lume should be stabilized. I dropped some watch parts on my floor, then grabbed the UV flashlight by mistake. I had the lights out (which can help finding tiny parts) There was a pile of dust that started glowing when the UV light passed over it. I think this came from my box of dust, which had some lumed hands in it. As I recall radium is only an alpha emitter, more likely the glow comes from the phosphors. I actually have quite a few things that glow in the dark after being exposed to light. I think tin is the active ingredient for that sort of paint.

I noticed that the lume on my Speedmaster seems to be spotty on the hour hand. Not something I would service myself. Although I have the same movement in a Tissot, which came as a box of loose parts. Also itching to start working on my Lemania, Lemania.

Hind-site is such a wonderful thing. I was in Switzerland in June, and took an unexpected trip to Neuchâtel. I could have dropped the speedy off in Biel/Bienne as the train went through there on the way back to Zurich.
