Apple Watch rash
I have developed a very bad rash on my inner arm (wrist) ,,,,,only had the band on a few hours ... this is a new series 4 with black sport band...i can send photo ...I think it’s the band?
Apple Watch
A very very small % of people are allergic to the watch or its band.
You can try washing the band since maybe the cause is something on the band, not the band itself.
If problem you can return the watch for a refund

You can purchase another type band, not one of the soft plastic ones.
