Recommendations for smart watch with Note 4 running CM 12.1

I messed up and bought a Samsung Gear S2 watch to go with my Galaxy Note 4. It requires initialization with Samsung Gear app on the phone. The watch won't do anything, even display the time, until initialization is complete. You get an error message about an incompatible operating system. So I returned the watch.

I need recommendations for smart watches that will work with a rooted phone running CM 12.1. Thanks.
