What this watch does is allow you to simply use it as a normal watch, with the ability to connect it to your iPhone/Android device and then use applications to either, change the song whilst it's playing, view what song you are listening to, or view who a text is from. I think that the best idea is being able to quickly view who the text is from and the first couple of words without having to take the phone out of your pocket, it is ingenious!
This is an absolutely fantastic idea, the fact that you are able to connect a watch to your iPhone/Android device, and then have the opportunity to purchase different looks for you watch. What this means is that if you do not like the look of the clock that you are using on the watch, you can simply go onto a website on your iPhone/Android device, and then download other apps and looks for it.
