Anyone ever try to restore a vintage dial?

[DrLindaPhD]

I saw this vintage Rolex and it can be purchased very reasonably. Everything works fine and except for the dial it is quite nice. I actually thought about trying to refurbish/restore/renew the dial myself as a sort of mini watch project. I'm just dying to take one of these apart and tinker with it and put it back together. I even found an on-line watch (horology) course and I'm thinking of taking it since it is only $75 and I'd like to learn about the workings.

Does this look worth restoring the dial or would you try to find a dial to replace it and is that even possible? Also, to restore the dial would you actually paint the dial? That's what I am thinking but I don't know the process but would love to observe someone restoring a dial like this. I've seen how wonderful a restored vintage can look. Does a restored vintage Rolex lose value over one that has never been restored?
