Many people are against screen protectors and cases on an ultra. It’s often compared to having a case for the Nokia phone, lol.

Personally, I’ve tried the Spigen case that has a built in screen protector which sucks because the sweat got trapped inside.

However, I currently have the Spigen Case as well as their screen protector, installed separately. Is it needed, no. Does it provide you with a peace of mind against scratches on your lovely watch/screen? Yes. It will help protect resale value. Plus, the case makes it much harder to accidently trigger the action button which was always a pet peeve of mine.

I dont have an ultra, but I am adamant about taking care of my things/protecting them so they stay in new condition. Alot of people in this thread seem to be against cases, covers, etc but I think you should invest in it! It provides protection, personality, and peace of mind. I currently have an SE Gen 2 with a dual rubber case screen cover. I don’t wear it daily, but If i ever start to use it more often the first thing I will be doing is switching to a hard plastic case and an individual protector. I do like my current protector because it covers the entire watch & is clear, but I find screen to be less sensitive with it and water tends to get trapped in between the case and watch.

Screen protector is probably unnecessary, but also basically not noticeable if you have one on.

If you insist on a bumper case, most have the protector built in. I’d suggest getting one with a seal so the screen doesn’t get wet if your watch gets wet since popping the case off, drying both and reattaching is annoying.

So I guess to answer your question: I suggest you go for two separate, assuming bumper case you select does not cover the screen.

The edges of the Ultra (2) ding fairly easily, but adding a full on case will increase the bulk of the watch, so hopefully you don’t mind that.
