I preordered my watch Friday morning, and I went by the Apple Store on Sunday because I wanted to see it... I didn't intend on making a try-on appointment, but the wait was only 10 minutes so I figured what the hell. The Apple sales guy mentioned that you can make/receive calls from the watch as long as it's on the same wifi network... does not need to be in bluetooth range. I haven't read anything to confirm this... does anyone know? It would be pretty useful for me, as at work we have a rather large campus and a wifi network covers all of it, and I often leave my 6+ on my desk when I'm someplace far away.... I image all features will work as long as you are on the same wifi... your phone doesn't have to be with you?
