Not sure why my other thread was locked, but, I figured to be fair I should post an update here. Wearing the watch looser definitely is the fix for me. I'm not used to wearing a watch this loose, but, it does prevent the rash. I'm also not sure why I have never had this happen before, but, since I changed bands and it still occurred and it is going away while wearing it looser. It is unlikely to be an issue with the watch itself. Guess I'm just getting old.
