I just got up out of bed. Went to wash my face and then back into the bedroom to get dressed. I reached for my watch and the backing came off. It was on the charger and all I did was take it off. No swimming, never any water contact. Nada. So now what? Apple has made me addicted to my watch, so do i have to send it in for repairs and be without? Can I exchange in store? This happen to anyone else?
