Hi
I’m looking to avoid replacing the glass on a vintage Art Deco watch which has a nasty scratch
Any suggestions or recommendations would be appreciated
Thank you

 

Are you sure it's a scratch and not a crack? Either way, I don't think that one is going to be repaired easily.

 

It does look like a crack. Is the crystal glass, or plastic? Either way, you really have few options.

 

It looks too deep and if that is the case, you’ll need a new crystal.
When I get scratches on my acrylic “crystals”, I polish either with toothpaste if very light or I use a product called acculuster which polishes acrylic using a cloth wheel.
