So we could use the iWatch connected to an iPhone running Apple Maps

  One of the main functions of iWatchwill be that of interconnecting with our iDevices and displaying information through a Wi-Fi or Bluetooth connection, and a designer thought to make us a demonstration for how we could be directed by Apple Maps. Basically, the iPhone application would send to iWatch directions for the location to which we are heading, the watch showing only an arrow pointing the distance to a point where we have to change the direction of travel.
