How to remove light scratches on the screen
Apple Watch Series 7, watchOS 8
The best results I have got are by the use of most common "homemade DIY method" by the use of coarse toothpaste (the one which have micro-beads in it). Just damp a part of the microfiber and rub on the glass surface of your watch. I use this method to remove scratches from my mom's eyeglasses (she's pretty carefree). Thus, it works well on it and I have even used this method a number of times to remove scratches from the mobile screen, watches and camera lens.
