When I was in the Apple Store, the guy told me something and I am not sure if it is true. He said that as long as my watch and iPhone are on the same wireless network, they will talk to each other regardless of distance or Bluetooth. He said he knows people that can leave their phone in a room and go out and mow the lawn the watch still communicates. If I leave my phone docked in the kitchen, and just go to another room, I get the red disconnected icon. Was what that guy said incorrect?
