I Have the same thing happening. I've been wearing the watch for months and its been fine. A couple of weeks ago I started to get a rash.. I cleaned my watch because i though it was soap or scum causing it. The rash cleared up and i started to wear the watch again yesterdaay and woke up to another rash (More red and lightly blistered). I don;t think it's from the HR monitor, because if not rashing under the watch.
I saw my GP and she said it looked like an allergic reaction, but why it only started about 6 months after I started wearing the watch, I'm not sure.
My friend just got me a new strap for the watch, for a bday gift (by Strap Studio, with "designed for Samsung on packaging) and it's leather on top, but they didn't realise it was still rubber on the under-side of strap. So far so good though! The rash has gone and I'm wearing the watch as normal.... just hope it doesn't do the same as the previous strap after a few months of wearing!
Excatly the same as i have on both hands :/
It showed up after few days of wearing. Red rash and in day or too skin peels off on that place. Tried on other hand - same. I am not allergic to anything.
I have a formal complaint in with Samsung Canada. They asked for pics of my wrist, the watch and the watch invoice. They said it will be about 4 days before I hear back. It'll be interesting what they have to say, considering that they have 30 pages of other people with similar reactions, which I pointed out .
