I've seen some horror stories about Moto's Warranty process, but personally and while I can't speak for phone warranty, my experience with them on the Moto360 was painless and fast. I (finally) has the back cracking issue on my 11-month-old watch, and as soon as I mentioned that, they issued a replacement that got to my door in a couple of days. I even got an extra charging cradle since they only request the watch to be sent in, no accessories. They even sent me a follow up e-mail and called me about a month afterwards to make sure I didn't have issues with the replacement.
