How about moto 360?

Motorola said that Moto 360 allows you to "gently turn your wrist" to get tips and notifications, including time, weather, navigation, etc., and also supports "OK Google" voice technology. It seems that under normal circumstances, its screen will turn off and wake up when necessary. As can be seen from several posters, Moto 360 looks like a round dial, which is very close to traditional watches. However, Motorola said that it will provide various shapes when it is released, and now it is just a prototype.
