I had put a deep scratch on the screen of my watch which, although not particularly distracting, bothered me. I didn’t want to buy a new watch so thought that I would try these screen protectors. I had watched a number of YouTube videos and feel that the one linked in the product description is not the most useful as they use a lot of LOCA (Liquid Optically Cured Adhesive) and it runs into the crown. I feel that this video is more helpful: https://youtu.be/RXAzJ3SfZGE?si=R6dHN_ms2WwJLj53 as it suggests using only 15 drops of LOCA for a 44mm screen. Also, I wound some thread around the crown and applied masking tape all around the edges of the watch to prevent the LOCA getting into the crown, speaker or microphone. There was still a bit of cleaning up to do around the edges but much less than if I had used most of the tube of adhesive as shown in the original video! Overall, installation was a bit fiddly but manageable. Don’t forget to remove the plastic protective film from the INSIDE surface of the screen before you install it!

The end result is very good. It looks as new. You can feel that the screen protector edges stand out a fraction but this is not visible except on close inspection.
