Hi there, I finally have a proper NOS Omega glass for my Constellation with the little logo. I noted that the glass is also not 100% perfect at he inside. The outside is no issue since you can clean this and give it the Poly treatment. What to do with the inside? I am afraid if I do something in there it might damage the logo inscription and that is of course one reason on it's own to put the new glass in so it need to stay perfect! Thanks,
You can polish the inside of the glass with Polywatch also...it won't harm the logo, but you need to make sure it's properly cleaned after.
