Apple

I have a fairly new Apple Watch, and just noticed that it's causing discoloration of my skin in the pattern of the sensors. It doesn't hurt, it basically looks like sunspots in a circular pattern just outside each sensor on the back of the watch. I've googled it relentlessly and can't find anything like this. When I contacted Apple ( I want to return the watch as this is concerning to me)....they initially acted concerned and elevated me to Fred in their safety division....and then, radio silence and they refuse to respond to me. Anyone else have this issue with their watch?
