I think someone mentioned somewhere that modern lume doesn’t patina as much, but this is all hearsay.
I do know old watches used radium and the compounds have changed nowadays
I seriously doubt modern watches of any sort will patina at all in our lifetimes.
Modern water resistance will seal out moisture. Modern paints and dyes are UV resistant.
Lume is also a completely different technology compared to vintage watches which relied on a mix of a radioactive compound and a phosphor that fluoresces when exposed to radiation, but which wears out over time.
Modern superluminova contains pigments which are charged by light, natural or artificial, and which then continuously emit the stored light energy until it runs out. Theoretically this charge/discharge cycle can be repeated infinitely but it remains to be seen whether that will be the case in practice.
No it’s different. Modern lume (since the 90’s) is strontium aluminate. Prior to that zinc sulfide was a common phosphorescence. Radium was often used as the energy source with zinc sulfide from 1910 up until it was banned in 1968. The radium dials typically show a lot of patina as it decayed, so much so that it’s pretty easy to spot a radium patina dial these days.
Faux patina turns into normal lume over time😬
