Apple watch burn on wrist?
I was recently told by Apple that the battery in an Apple Watch could not cause a burn to my skin if it leaked. I was wearing my Apple Watch when I felt a burn/shock, I took it off immediately notice a small blister on my wrist. I examine the back of the watch and where one of the sensors was, was corrosion and a hole. The sensor was missing. There was some corrosion around the hole where the sensor had been. Apple has determined that it was accidental damage caused by the user. My questions are: if the watch battery could not have caused the burn, what did? How could the sensor be damaged with normal wearing? I'm nervous to purchase a new watch a) bc I don't want to get burned again b) I don't want to spend the $ if the watch isn't going to last 3 years.
Any suggestions?
