Flex - Any non-original part (including Rolex service parts, if they differ from the OEM part) in a Rolex watch will (negatively) affect its ultimate value to serious collectors. But so can a damaged dial. It is a balancing game & you have to make an executive decision. Were the watch mine, having seen the new picture, I would have Universal refinish the dial.
However, & I think this is your goal too, for non-tool watches, I prefer a watch that looks like it just came back from Rolex service, as opposed to a vintage watch that 'looks its age'. The dial you receive back from Universal will look, for all intents & purposes, almost exactly like 1 of those NOS dials you see popping up on TZ every once in awhile that makes people (like me) pant & drool.
Still, on the other-other hand -- If you use the dial as-is (unrefinished), no one who looks at the finished watch will ever believe it is anything other than (a freshly-serviced) gen. The age & patina on that dial is unmistakably genuine, which adds alot of credibility to your watch.
So, you really cannot go wrong whichever way you decide to go. Just make absolutely sure you go with a gen (& age/model correct) bracelet or strap
