Yup, the watch piggybacks on WiFi authentication from the phone. Once you store the SSID and PSK for a network on your phone, the watch can log in independently, and you can take/make phone calls and SMS. I've done this when I left the phone at home by accident.

It's not the just the watch. All my devices will connect to a new wifi if one does.
