*All* smart watches need tying them to a smart phone...
which makes sense given memory, processing power and battery limitations. Today a computer is pretty much useless without being tied to the internet (with the extreme example of Google's Chrome OS), in fact even more objects get their tie ('internet of things').
Moreover, even Google realised that in order to boost sales of Android Watch OS driven devices to meaningful numbers they need to find a way to enable tying to Apple'e iPhone...
So, it is not nonsense but a paradigm change which is pushing forward with force (whether we like it or not).
