Bangle JS 2 screen scratched, is there any way to repair it other than buying a new screen?

Hey folks, I seem to have picked up a couple of noticeable scratches on my bangle js 2. I believe the screen is glass, does anybody know if it's the kind you can sand down and if so what would be best for this? It works perfectly but the scratches are annoying. I don't fancy warming the glue up and opening things to replace the screen manually.

Thanks!
