Wrist Deformation and Skin Alterations

I have been wearing my Nike series 4 watch since it came out and recently I have noticed a slight indentation on my wrist where the watch sits in the skin feels a lot thinner than it used to. I also noticed color change on the wrist where I wear my watch, which is to be expected after wearing a watch for so long, the location where the sensor sits on my wrist feels mushy. I can see some redness. It definitely feels like strange skin not my own. I would give up on wearing the watch, but it is so useful that I will continue to wear. It may be a smaller, less intrusive, more compact, ergonomic, material, friendly watch might make me

Upgrade, so do I have to deal with this one until then I’m just curious, is it just me or does this watch change everybody?
