Do You Need a Screen Protector for Your Apple Watch?
If you're worried that you'll scratch up the screen on your Apple Watch, you can easily buy and install a screen protector for it. But should you be worried about it in the first place?
I know a lot of people who have been in the market for an Apple Watch, but have backed out because they're worried the screen would get scratched up fairly easily based on daily use—it's easy for a watch to bump against various objects and scuff it up.
Depending on what model of Apple Watch you have, the display glass may be more durable than other models.
With the newer Series 4 Apple Watch (as well as some previous generations), the stainless steel model comes with display glass made out of sapphire crystal, which sounds more like marketing fluff, but it's actually a really nice feature if you're paranoid about scratching up the screen.
Sapphire crystal glass is made from the sapphire gemstone, which is the third-hardest material on earth behind diamond and moissanite, so it's incredibly resistant to scratches. Or at least it should be.
JerryRigEverything, a YouTube channel dedicated to performing durability tests on consumer electronics, performed a scratch test on a Series 3 Apple Watch with a sapphire crystal screen and discovered that it wasn't quite as scratch resistant as it could be, noting that the sapphire wasn't as pure as the Tissot watch he was comparing it to, which also has sapphire crystal glass.
