Excellent screen protector perfect fit for my Apple Watch 4

Although I mention some minor cons, it attached the screen well (and offered enough to reinstall.

Easiest screen protector you can install for such a small screen.

For those that do not want a thick case, try this to protect your screen from scratches

The picture shows the watch with the protective screen already installed

then it means it’s a great screen protector.

Does not cover whole screen (already described), a bit more complicated to install (must watch how to install video clip), Feel the film's cutting plane whenever you swipe the watch screen, it is really thin though
