Apple might have named their next-big-thing as Apple-Watch (such a long name) only in regards to value their brand rather than let grow the individuality of their product, it's not the brand but the offering that builds the brand. The iPhone, the iPad, the iPod will always remain influential in it's own separate identity.

Steve Jobs believed, “If you can control the meaning of words, you can control the people who must use the words". Names, and words in general, have a meaningful history that influences their use, whether you know it or not. Steve Jobs believed individual, imaginative, innocence and all the other words it came to stood for began with the letter 'i' and hence he wanted to evoke and shape the same 'i'mportance to the individual products he brought. Apple-watch is similarly another product meant with a destiny, for something revolutionary that renders service to this world and hence change lives. It is essential to realise the principles and aesthetics given importance by Sir Steve Jobs and so is the request that they, the people now taking care of Apple, realises this. Therefore, not to rename the every product made by Apple but this particular can be renamed as 'iWatch' as it's something more personal than any other.
