Posting on behalf of my wife. I got her a vivoactive 3 for xmas. Since wearing it she have developed a burn patch area on her arm under the optical sensor. I have photos and her doctor has indicated that the skin is damaged. The skin damage is in a rectangle shape directly under the area where the three green lights sit for the optical HR.
She wears it 24/7 except for when she showers. She cleans the sensor daily and drys her arm fully before putting the watch back on after the shower. She has now moved the watch to the other arm and the same appears to be happening there. This process takes a few days / week of continued wear to occur.
Are others seeing this issue? is it a burn or a rash? The first arm is still red with a raised hard red skin area even after a week of wearing it on the other arm.
The Doctor doesnt think its a rash but we have a topical cream just in case.
thanks
Richard
