No matter how careful you are, watch glasses made of plastic or glass get scratched over time due to daily use. This is mainly due to the exposed position of the watch on the wrist – because you can quickly scrape it along the wall of a house or get stuck somewhere else. Unlike a scratch on your glasses, it is usually only the beauty of the watch that is impaired and rarely its functionality. Nevertheless, scratches are simply annoying and you don’t want to be reminded of them every day when you look at your watch.
