The PanzerGlass Full Body Screen Protector does exactly what I expect: protect my Apple Watch from all sides. Unfortunately, because of the thick edges, I can no longer see the color of my smartwatch.
Apply
Installing was a lot easier than expected. It was impossible for me to stick the screen protector crookedly, because you click it on the screen. After that, the screen protector sucked on itself. So apple egg! Beforehand I had to clean the screen well so that there were no dust underneath, so you prevent air bubbles.
Appearance
I didn't expect the black border around the screen protector to cover the entire front of my Apple Watch. It's almost like a case and screen protector in one. That's why it all seems like a whole, it's not noticeable that there is a screen protector on my screen. I regret that the thick bezel covers the color of my Apple Watch and makes it a bit bigger and thicker.
In use
When I navigate through my touchscreen, I actually don't notice the screen protector. Swiping is just as smooth. However, the screen protector is very thick on the sides, so that it closes around the bezel. This makes scrolling a little less easy. I don't feel the screen protector when I wear my watch, so it's nice.
Protection
So the black border is on the thick side, protecting both my screen and the sides. Very handy since I sometimes bump my Watch against a table edge or door frame. So I have to be a little less careful with it.
I tested the screen protector with black edge, you also have a transparent version.
