Don't know, but to throw in:
The watch and phone do not share the same number. They are each provisioned as their own and use NumberSync (or whatever ATT/V/TM calls their particular service) to make it look like they are sharing a number. So although you have two devices, they are networked together to be one. Given that, I would assume that they work just like the existing watched, iPads, and Macs. When I get a call, they all ring. No reason to think this would be different unless I changed by preferences. I'd almost promise that you could not make independent calls on each. Unless once call was your typical phone call and the other some VOIP type service like Team speak of Skype or something.

This is an assumption. It could be that the watch is NOT attached to a tower when it knows that it is currently connected to its master phone. In this case it could save battery by not making unneeded "check ins" and use the phone for this service (like it can also do for GPS and other off loaded services). The LTE watch may only take on an active connection when its host cannot be connected to. We may never know, anyone got a sting ray device to test is out? ;-)TheShadowKnows! said:Both, iPhone and AW3.LTE are connected to the cellular carrier (i.e. show the carrier's strength signal):
