Got my Apple Watch on 5/1/15. I tripped and fell 6 days later, and I cracked the glass across the top and down the side. I contacted Apple Support online and they had me call Apple Support. They are actually replacing my Watch because I called and told them the truth, was very nice when explaining what had happened, but I did not expect a totally free replacement! They estimated I get a new one (even though it's heading to the repair department in Pennsylvania) of 3-5 days turnaround. I did not purchase the Apple Care+ program and they are not even charging me a deductible or any shipping fee! Thanks Apple!
Oh Thank you, by the way I tripped UP the steps, on my front porch, while breaking in a new pair of sandals for an upcoming cruise.. Only harm done was the cracked watch face, not mine.
