For me, the best available at the time SmartWatch!

Pro:
The bright design looks again better than the black. There are countless Watch Faces, you can for example adjust the app from Intellicom to 100% according to their own ideas. From a Watchface that 100% is black and only one pointer has to a fully digital Watchface with display of weather, temperature, barometer, pedometer, date, time, here and elsewhere, and so on, everything is possible.
Another highlight is the wireless charging station!
The pulse measurement functions help to monitor its own activities with me without problems, apps like Google or Moto Body Fit. With a Bluetooth headset you can use the clock while running as a music player, you can store 3GB of music on it.

Cons:
The perceived battery life is initially abundant short. But that is always the fact that one initially playing around a lot with the clock. Especially the exchange and customizing Watch Faces eats an awful lot of energy. If one has finished first, the battery lasts even in Ambient mode is enabled by loose 18 hours. Evening commitment the clock anyway from, and then slumbers forward to the next day. It is fully recharged within an hour. More can not ask, considering the scope of the possibilities and the elegant design. The Samsung S Wear has a better term, but is also more of a mobile phone with bracelet as a clock.

Conclusion:
The Watch R by LG has better battery life but a much smaller screen. The Moto 360 is throughout equal to the Watch R, but has only a very narrow margin.
Anyone who is not satisfied with the battery life, the clock should one day give the chance to work without messing around.
