You cannot call it innovative if it comes out with the same core features as the current smart watches already out today. It may well be a disruptor though since it's Apple, and people will line up in droves to buy it regardless of what other competing products are out there.
That depends on what do you mean by innovation. According to Wikipedia, Innovation is a new idea, device or process. Innovation differs from invention in that innovation refers to the use of a better and, as a result, novel idea or method, whereas invention refers more directly to the creation of the idea or method itself. That to me sounds very Apple.
Can Apple Watch be viewed as the application of better solutions that meet new requirements, inarticulated needs, or existing market needs? Regardless of who came first and called their product SmartWatch or whatever, an imitating functions based on rumours surrounding Apple Watch, we all knew Apple has been working on it far too long before any rumours leaked. Can those Android devices claimed they are first innovating Smart Watch?
