If you can find, yes. As your watch is on your arm, you’re bound to hit stuff like doors, windows, other people, keys, buttons on shirts. I need to replace mine on the Gen4 about every 3/4 months because of a bad hit.

Would the screen be scratched or broken? Maybe, but the protector does fine to catch the pain and it’s easily replaced. Do find a glass one instead of plastic, as it gives a good feel and can absorb the energy by shattering.

I'm 4 days into owning mine and by just casually hanging out with friends over the weekend I got 3 nice little scratches on it. I've stopped wearing mine until my screen protector comes in, I'd advise you to do the same if you don't want any scratches. Seems like it's reallllll easy to scuff it up.
