With a screen protector, you protect the screen of your Apple Watch from scratches and dirt. Your Apple Watch screen then stays intact if you accidentally scrape it across a wall. Some screen protectors look good longer, thanks to a self-healing coating. Small scratches then disappear on their own. There are also screen protectors with an antibacterial layer. Bacteria don't stand a chance on these screen protectors. Choose a glass Apple Watch screen protector for the best protection, because a glass screen protector provides better protection for your Apple Watch than a plastic screen protector.
