[Q] Smartwatch 2 connected notification topic

I would appreciate if anybody could give me a suggestion on how to get rid of this "Smartwatch 2 connected" notification tile which can't be dismissed. It's especially annoying now with Android 5 as it's always visible on the front screen. I have LG G3, but I don't think it relevant to phone model as the notification used to be visible on my Nexus 4 device too.
