Mine was turned off and on recently and it popped back up. Just say " OK Google what's the weather today?" After it shows the info it will go away. Just tested it on mine
Mine did that too after a reset. I think it's part of "get tips" feature in Android wear. You can try disabling i . That message did disappear after awhile as I used the ok google function.
Actually resetting it and my phone drove numbersync mad. The long and the short is that it takes a while for the system to settle down and generate a new sync code.
