Apple Watch defective Screen

Hi.! I recently switched to apple, encouraged by my son and friends.

I bought an apple watch series 5 in January, and I wanted to ask maybe something silly, but still needed to clarify my issue with the watch.

Simple question: how weak is the protective screen..? As you can guess, my watch fell down from less than 3 feet high, and it just broke.

The del is that I was wondering if is there any service note abut some specific models, because I've been researching a little, and most of the time the screen just shatters all over, but in my case, the right upper corner just felt apart, and little pieces of plastic / glass (I just don't know) were in my hands when I lifted it up.

The thing is that I wasn't expecting that the watch were this weak, so that's why I'm asking if there's a chance that my specific model maybe has a defective part that led to this behavior, or if this is just what it's expected in most of the cases.

Since is a brand new device, is there any chance to buy apple care so I can use it to replace it, or this is not the way it works..?

I'll appreciate any comments.

Regards.
