Ion x glass...Apple watch sport
You can't.
Are you sure it is scratched?
If so your choices are have the crystal replaced or whole watch if you have AC+ or put a screen protector (yuk) on it to hide the scratches.
Bang it up some more so they even out and you stop caring. Then get on with learning how to stop stop worrying and love the watch.Anyone know anyway to get rid of small hardly noticeable surface scratches? The fact I know they are there bothers the hell put of me
