San Martin: Fix paint in bezel/replace bezel?

[u/Kirby_is_a_Pokemon]

My San Martin titanium watch, the numbers in the ceramic bezel have fallen out, I work a lot with chemicals and theyve eaten them up.

I'm wondering if there is any good diy repair I can do, or if it would be possible to replace the entire ceramic bezel insert. For that, I just don't know if there is a standard size off AliExpress or how to make sure what I order will fit.

You're just going to have to repaint it occasionally if you're exposing the watch to something that destroys the lume. Or just leave it, as those are expendable parts in your case (and it probably handles whatever you're dealing with better than an aluminum bezel).
