Lume question

[32' Sub]

I have an N series Sub circa 1991.
The lume on the hands and dial is no longer glowing. The "dot" (please tell me the correct term for this) still glows.
If I wanted the dial and hands to glow again, what would my options be?
Repainting the original-
re-dialing-
trade up to a newer Sub-
or should I leave it alone?
What should I expect to pay for any of these options?

Thanks in advance!
