I have recieved multiple itchy red spots on both of my arms (it has also spread to my elbows) after wearing samsung galaxy watch I recently purchased. I have never had any problems with other watches or metals.
No, I have a leather strap and have used it on other watches, so thats not the problem. I dont have spots around my wrist, but i have one right under where the watch is. From there it spread to my upper arms and elbows.
I just bought a Galaxy watch 3 and i have a rash under the watch directly. Hate to say it but I have to return this. I really wish Samsung would invest in some R&D as to why this happens with their watches. And btw Ive never had a skin rash until I started wearing this watch, not sure I'll buy a samsung wearable again.
