apple watch sudden screen shatter

Isn't that sooo crazy! My unscratched, perfect screen shattered overnight on the charger. I spoke with someone on the phone first who said to send my 4-month-old watch in and see if it would be covered by warranty. But, I was impatient and took it in to the Apple Store. They checked it out and said the screen had to have been damaged externally--they said the battery wasn't swollen--but they would send it in under warranty just to see. I got an email saying the techs checked my broken watch out and that I would have to pay $229 to fix the screen because it was due to external damage. I called and ended up speaking with a senior advisor who told me to "not lose hope" but that they would send it back to me damaged. Upon receiving the damaged watch, I was supposed to email the senior advisor and let her know I received it. So, I did. At that point, the senior advisor said she did some research and I could send my watch in again and Apple would fix or replace it. I got a new watch back (different serial number). I'm grateful they fixed my watch that was obviously defective. I hope Apple kept my watch and is looking at it with a fine-tooth comb to see if they can figure out what caused mine to break and fix the problem to help everyone who is having this same issue. I count myself lucky! But, I did have a nice fitbit picked out to replace my Apple watch! Haha. If my watch breaks again soon, I really am not going to buy another. Although I still like the bazillion other Apple products our family owns and uses.
