When I was a kid, I looked at the Ranger, so I pretended to be Michael Nittkit. This is my watch. However, there are real watches now and I can do more things. I don't feel like I was 5 years old excited. Smartwatches has existed for more than a decade (Microsoft SPOT), but the category has not evolved into the same smart phone. The problem is that there are no common platforms for third-party applications, which means there is little potential for growth. 
In addition, there does not seem to be any vision. Some watches made SIM cards for Android phones and small touch screens, and they tried to build their own platform to attract developers. Some people even try to combine fitness and smartwatches into one device. What's worse is that in most of today's watch markets so-called "fashionable challenges", they are simply not attractive enough to attract the public. Google's Android platform solution is to increase market share and developer support.
