Preserving/halting Patina

Forgive me if this is a dumb question, or a tired one.

A dial with nice patina on the lume plots, let say—tritium from the 80s. If one purchases that because it looks really fantastic but doesn’t want it to progress much/any more but also would like to wear the watch regularly, is that a realistic hope? Do people swap out original crystals for ones with modern UV coatings perhaps? (Hanging onto the original too, of course.) Would that halt or dramatically slow further patination?

This is still in the realm of hypothetical for me, but as I get more interested in vintage with age-character, I’m beginning to wonder about longevity too. Thanks!

Lume plots (tritium) turn dark, turn grey, and eventually black when they soak up moisture.

If your watch has been kept dry, and you want to keep it looking it's best, make sure to have your watchmaker replace the seals, and if necessary, replace a cracked or damaged crystal or crown.

Appreciate the replies.

I'm attracted to the some of the late-70s to mid-80s watches (speedies and subs, mostly) that have what gets described as "pumpkin" dials---that gorgeous, dark orange tritium patina. (This 1984 Submariner is a perfect example.) Just wondering whether that's a look that will last. My interest wanes when it comes to "spider dials" and other aging effects that strike me more as damage than distinction, but I know that all comes down to personal opinion.
