I've got an Android Wear device that sits in a drawer because it is pretty useless. Charging it every night is more hassle than it's worth. I don't like wearing watches though. However now I wear a fitness tracker (Garmin Forerunner 235) because it is useful to me. It lasts 5 days on battery, it has GPS built in so I don't take my phone when I run anymore, it tracks my sleep and has all day HR monitoring and best of all it connects to my cycling sensors so it replaces my cycling computer.

It also has basic notification support but that is the least useful part. Getting notifications on a watch saves me about 2 seconds and is not worth wearing a watch and charging it every night.
