Late last night while wearing my watch, I noticed it was really hot, to the point of needing to take it off. When taking it off, I noticed the screen was blank and the watch was unresponsive. Battery should have been around 50% or so, so it wasn't out of battery. But nothing I did could get the watch going again. Force Restart didn't work. Putting it on the charger did nothing but make it hotter. My iPhone showed it was not connected to the watch, nothing. I chatted with Apple Watch support last night and they are having an iPhone specialist call me today(the Apple Watch support team didn't have the ability to handle his situation, apparently ). This morning, the watch cooled down, but force restart still does nothing. Putting it on the charger does nothing. Plugging into the computer for iTunes (would this do anything anyway?) does nothing. It must be dead. This 38mm Silver Aluminum watch (with green band) has been babied. It has not been dropped nor has it been hit against anything. It hasn't touched water but has been exposed to my sweat when working out several times over the last few days. We'll see what Apple says, but I think I'm just going to return it and wait on my 42mm Space Gray that's on order. EDIT: Apple determined that the watch was indeed defective and/or something was definitely wrong with it. After all the trouble shooting tips they had, they couldn't not get it to show life. I had the option of returning it or getting a replacement. Since I really want a 42mm, I decided to just return the watch for a full refund and wait on my 42mm Sport SG BSB.
