Has anyone else experienced a red mark on skin while wearing iWatch? Why is this happening and is it dangerous?
It appears that you may be allergic to one or more of the components the Watch is made of. See this, Wearing your Apple Watch - Apple Support and then see your doctor to have them diagnose the problem.
Okay, but the Series 4 watch backing is somewhat different than the other ones. Either way, the only way to determine what that is on your wrist is to consult a physician. Random users on an internet forum are not going to be able to determine that.
Thanks I should mention this is a series 4 watch never had this issue with the previous watch versions.
