When my smartwatch had trouble pairing I used a couple of methods to try and get it connected securely again (1) First I powered on/off both my devices. (2) Then I made my phone "forget" the smart watch. (3) Re-pair the smartwatch again If that doesn't work then uninstalling the Android Wear App then reinstalling works when nothing else seems to.
