Spigen Eliteshield EZ Fit Screen Protector for Google Pixel Watch 4/3/2/1 41mm, Installation Kit included, Anti Scratch, Crystal Clear - 2 Pack

Excellent protection and easy to apply. Would recommend.

I did not have much luck with this on a Pixel Watch 3. The applicator wasn't all that much use, it was fiddly as it lifted the screen protector when you went to peel it off and ended up slightly off center. It was crystal clear though. I then noticed after a couple of nights it was getting even more off center! I managed to carefully peel it back off and reapplied it better than with the applicator. Unfortunately after a couple of days it was massively off center again.Maybe I got a dodgy one, I don't know. I put the other one on my old Pixel Watch 2 which I gave to my brother. If that holds up better then I'll update the review if I can.

Fitted to my Galaxy Watch Ultra without any issues; took all of 30 seconds

Made a mistake of removing the wrong film when installing it but had a spare one which installed just fine. Installation was super easy and the screen protector is perfectly aligned with help of the alignment tool. Highly recommended

These are amazing when you get it to work, application is simple, clean watch, peel back off, spray, apply, squidgy bubbles out peel off lat layer... Only issue first time was when I peeled the last layer off it took the actual protector off with it... Luckily worked second time... However I'm unhappy I no longer have a spare.Very expensive for a single protector at the end of the day.

First one came off within a week. Second one wouldn't even stick. I'd avoid this.
