I did this for my mom, who also refuses to switch to an iPhone. I got a cheapo/locked/unactivated 6s and paired the watch (non-cellular) to it. It gives me some peace of mind that at least it covers her at home; there have been a couple of times it got activated (fortunately false positives) and I can confirm that it definitely calls 911 in this scenario right from the watch if she doesn't acknowledge its warning in time.
