I've had the Gear S3 Classic since launch, and I wear it every day. I only take it off to shower or charge.
Recently, I developed an irritation on my wrist under the edge of the watch body. It developed into blisters and then to a dry itchy rash. I kept the watch off for a couple of weeks until it healed, and then began wearing the watch again. The blisters/rash once again developed. I tried putting a large patch bandaid on the rash, but that didn't help. I just switched to my other wrist to see if the rash develops there too.
Is my watch defective? Anyone else experiencing something this extreme?
I had similar issue, then I changed the band from a rubber one to leather and now I'm OK.
