I have a vintage Tag chrono that has a moderately scratched glass crystal. I have some experience polishing plastic crystals but not much with glass. Is there any way to polish glass crystals effectively? Thanks for any help with this.
I have polished glass on cars and watches over several years using the glass polishing kit from Eastwood (Eastwood.com). The crystal has to be thick enough to take a little hand pressure. It takes times and patience, unlike plastic polishing, but works well. If scratches are deep then replacement of the crystal is recommended.
