No screen protector can fit properly on an Apple Watch without being annoying and getting snagged every now and then in pockets, etc. End of story

I'm not giving it 1 star just because I like the company, but unfortunately this product is unacceptable. I was reading reviews and thought it couldn't be, people just aren't following the instructions properly. The package comes with many accessories to help you apply the film (2 alcohol wipes, a screen cloth, dust stickers, a tool to press out air and prevent bubbles, a positioning base, and 2 films). The one in the photo is the second film I put on an hour ago. When I put on the first one, it bubbled and I thought I made a mistake, so I removed it and applied the second one PERFECTLY! And yet, after an hour, what you see happened. Unfortunately, Spigen made a mistake with the adhesive on the film and it doesn't sit well. You'll waste your time, effort, and money. You're a thousand times better off getting the other film (which I had before) from the same company, which is harder to apply but if you do it right, it sits perfectly.

It doesn't fit perfectly, it holds air inside and you lose touch response. I was not satisfied at all.

It's a shame because Spigen had accustomed us to premium products at very good prices. Mediocre evaluation for a mediocre glass protector. I recommend it, but if you are compulsive, it's better not to "dare" it.

It is not a tempered glass, it is a thick plastic film. We definitely do not recommend it, it is better to get the Spigen gelatin

The screen protector is extremely difficult to install, and even on a brand new watch, it leaves bubbles after a few days.

Indeed, with great surprise, I confirm that it affects the touch response.
Easy installation, good quality, etc.
But it has this downside.
For now, it doesn't bother me much.
In the long run, it will show.

The worst thing about the spigen name.. very poor fit, it cuts off the screen with this unnecessary frame they have added, plus the case they have for the watch 8 lifted the glass and filled it with bubbles for free, costing 13.7.

For the series 8, it doesn't work at all, it cuts the screen, you can't do touch, I tried both and I threw them both, it really gets on your nerves

From an installation perspective, the first one went to waste as dust entered from underneath and when I lifted it to remove it, the "glass" cracked. The second one fit well and so far has no bubbles, however:

1) indeed, the black bezel cuts off part of the screen as it blocks elements near the curvature point.
2) it easily gets scratched.
3) it scrapes the finger on the corners.
4) the touch sometimes doesn't work as well.

If I find something better, I wouldn't buy it again. I don't know if the alternative membrane + case is a better choice.

I had the same screen protector for the smaller Apple Watch, which fit perfectly and I had no issues. I would buy 2 at a time and change them every 3 months. Unfortunately, it does not fit the larger Apple Watch. Despite the correct and thorough application, bubbles appear on the second day. This happened with both screen protectors included in the package.

Although I am a fan of Spigen (glass protectors, cases, etc.), this glass protector was a failure. Very difficult to apply and loss of touch sensitivity. I do not recommend it.. (Apple Watch 8 45mm)

I don't think it's for 45mm because it looks like a small glass and it doesn't cover the whole watch, resulting in it eating up from the screen. Too bad, I expected it to be better.

Although satisfied with Spigen's phone protections, for the watch it is a failure. As shown in the photo, the protection gets air from the corners and creates bubbles. I should note that during application there were no bubbles, they appeared after one day of use!

The application on the Apple watch was easy and didn't take me long, but the result didn't impress me much as it covers the edges of the S7 screen and I understand that because if I look at the Apple watch from the side, I can see the letters on the dial. A few bubbles appeared, which don't bother me much. I would recommend it to people who don't mind if the appearance of the watch is slightly altered and if they lose a few millimeters from the screen and want to protect their device.

It requires a lot of attention during installation! Watch the video first!
The edge of the screen is lost due to the black frame it has! Under no circumstances should it cost more than 10€.
