What (if any) restoration/work can be done to a dial without hurting value?

[Eph]

I recently took a gamble on a Tudor Sub off eBay (from Japan), and had the watch delivered directly to a well-known restoration shop not far from the seller. I plan to get the jubilee bracelet tightened up and the watch serviced so this can become a daily wearer! I chose to have it shipped directly to the restorer because 1) I save on Taxes by not having it shipped directly to me, 2) the service there is about 1/3 the price of a service here, 3) This person has a stellar reputation for working miracles on stretched jubliees.

That said, I'm also wondering if the dial could have any work done too without it hurting the value. The dial/hands have yellowed quite a bit and likely don't glow. Glowing hands will be somewhat useful to me as this will be a daily wearer, but I don't want to kill the value in case I decide to sell one day. Does a re-lume hurt value? Also, will a re-lume essentially replace the patina the watch has developed over time so the hour markers/hands will now be white (or an artificial patina?). Anything else I should be considering?

Here's my original post with a photo, from before I purchased the watch!

Would love any thoughts or suggestions.

Thanks!
