Virtually every smartwatch owner has had that moment of exasperated frustration when we bang our watch screen against a wall or a chair. A good screen protector can help with that. While the new Apple Watch Series 9 already boasts a fairly scratch-resistant screen, employing a sapphire-crystal glass that you often find in Rolex and other luxury watches, it doesn't guarantee complete scratch-safety.

Fortunately for Apple Watch owners, shopping for a screen protector is pretty easy. Apple Watch Series 9 watches are 41mm and 45mm, so all you have to do is find the corresponding size protector and some products make it even easier with installation tools to make it a true no-fuss process from application to protection.

Best Apple Watch Series 9 screen protectors: Which one is best for you?

First, it comes down to preference. If you prefer glass, then any of the glass screen protectors listed above will do a good job. Those who enjoy softer screen protectors have their choice of a few options above as well. The only time it gets super specific is if you want something special, like the IQShield matte screen protector or the Cuteey privacy screen protector.

In general, we think the Ymhml soft screen protectors are a good pick for beginners since it has an applicator tool that'll help you get it on there more easily. All screen protectors are precision cut to fit the device they're designed for, so the application will require precision no matter which one you choose.

How should I prepare my Apple Watch Series 9 for screen protector installation?

The installation of all screen protectors is about the same. You'll first want to remove any oil, dirt, fingerprints, and residues from your Apple Watch screen. Clean it and wipe it down as you normally would. A nifty trick is using a sticker to pull up any small granules of dust that a cloth might leave behind. Those dust specs can cause bubbles even if your installation is otherwise perfect.

From there, simply follow the instructions from the screen protector manufacturer. The vast majority of them have instructions either in written or video format. Some are dry installs where you just plop the screen protector on there and others are wet installs where an adhesive liquid is applied first. If you mess up, remove the screen protector and try again.

Does Apple recommend a screen protector for Apple Watches?

No, Apple has complete faith in its sapphire-glass screens. You can still add one. It won't void your warranty or anything like that. Apple simply doesn't think you need one.

Should I get a case with a built-in screen protector or a standalone screen protector for my Apple Watch?

That's a great question. It's mostly a matter of preference. Cases with built-in screen protectors add more protection to the Apple Watch itself, but the screen protector won't be as flush and flawless as a properly applied screen protector. It's ultimately up to you and what you want to do.
