Continuous pairing request from a smart watch
It is an issue across most Android wear devices, Wear 2.0 and any watch.
You'll see this issue all over the Internet.
I have two Moto 360's and both constantly have pair requests with my Android 7 Motorola Droid 2.
I have factory reset both, followed Google's directions and still does it.
Hopefully Wear OS 3.0 will fix it, but I've heard both of my watches are not getting that update, which is BS.
