When an android wear watch disconnects/reconnects from Bluetooth does it vibrate? If so, what happens if it constantly disconnects/reconnects? A bunch of vibrations?
Try factory resetting the watch and then setting it up and don't use your phone or watch for 3 hours i found this fix this problem of disconnecting but i can totally be off base you might just be leaving you phone behind and you can disable on some watches what do you have?
