I would expect acrylic on a 1940s watch.Does that only work on acrylic? I have a 1940's Bulova with some scratches. I assume the crystal is glass.
Thanks for the info. Is there an easy way for a person with no knowledge (like me) to tell if my Bulova is glass or acrylic?I would expect acrylic on a 1940s watch.
Silicate ('mineral') glass is a lot harder to polish and really needs a machine to grind out a scratch. If your Bulova really is glass, it would be easier to get it replaced with acrylic.
