·I sometimes find it hard to distinguish between "patina" and "damage".
I get that tritium lume sponges or shrivels up a little bit naturally due to age, but sometimes it darkens?
I get that some dials change color over time due to UV light, but sometimes random "spots" appear on it?
I have no base knowledge on chemistry to understand why these happen.
This is why I find it hard to get into vintage watches. The chemistry behind "patina" is too hard to fully understand.
