You protect the screen of your smartwatch with a screen protector. The screen of your new smartwatch stays like new for longer that way. You prevent scratches and dents in the screen. A glass screen protector protects your smartwatch better than a plastic screen protector. Glass is harder and remains scratch-free for longer. A glass screen protector feels the same as the screen itself. Make sure you buy a screen protector that is suitable for your smartwatch model.
