Initially, it created a ring around the perimeter where it did not fit on the screen, resulting in an unpleasant appearance.
In the first few days of having it, I would wake up and it would be misaligned, requiring me to readjust it.
This created even larger gaps and bubbles around the edges.
One month later, without having bumped it anywhere, it developed a small crack, and a few hours later, a fissure appeared across the entire surface.
I will also try the second one that came in the package, and if I have the same result again, I will prefer a glass protector from a different brand.

The glass fits very well on the watch, it doesn't bubble and doesn't affect the image. It's like there's no glass on the watch. Also, it is very easy to install

It does not apply well, I bought 2 to be sure and still I was not satisfied, it leaves gaps all around and in a few days it deflated

Easy to install and has saved the screen from brutal hits on corners without breaking itself. It comes with 2 in each package, so I have protection for a while. I will get more to have in stock

The installation is easy, without bubbles. It covers the entire screen and there is no difference in the periphery, nor does it affect the brightness or touch function of the watch. As for the durability of the glass over time and the level of protection it provides (e.g. against scratches or impacts), I have no opinion because until today (fortunately) I haven't experienced any incidents or accidents.
