Apple Watch series 3

I got a https://www.bestbuy.com/site/belkin-screenforce-ultracurve-screen-protector-for- apple-watch-series-2-38mm/6073213.p?skuI… and when I first put it on the touch screen sensitivity was crap. After looking at it closer I saw it was off center, just barely. I reapplied it making sure it was centered this time and it has been fine ever since. Good luck.

A tempered glass screen protector will solve your issues.

I have the original Apple Watch without a screen protector, and I don't have any damage to the screen ( and I wear my watch every day).

The reason for this is because the Apple Watch, like it's older siblings the iPhone and the iPad, is designed to be used without a screen protector. The screen has many layers of protection already on it along with the glass being much harder than regular glass. Quite honestly, you are more likely to scratch the metal bezel surrounding the screen than the screen itself.

As far as the issues working, the Apple Watch is designed to "see" (for lack of a better word) with specific amounts of pressure. When you put a case or screen protector on the Watch, it throws the calibration off. On an iPhone and iPad, it simply makes the device work harder (which can shorten the lifespan). On an Apple Watch where the size and tolerances are so much more exact, it can and likely will stop it from working properly.

FWIW, I'm on my third Apple Watch (I upgrade when a new one is released), and all my leftovers have found happy, loving homes and are still running fine and none of them have ever had a screen protector.
