The problem with moving everything you do from a nice screen to a voice based gadget on your wrist is that the main source of interaction, the Internet, is broken.
If the Internet was made up of proper semantic tagging, and actual useful, machine parsable information, then yeah, sure, make a 'watch' that can answer your spoken queries with meaningful information. Unfortunately, the Internet is so far gone as far as easy information retrieval is concerned, that even the most simplest of queries needs significant backend development of APIs and data re-formatting.
Even if it were doable on a large-data scale your conversations with your watch would go like this:
User: Watch, When is the Guns'N'Roses concert on in London?
Watch: Hi, I'm about to tell you 'when is the Guns'N'Roses concert on in London',
but first here is an advert!
Watch: *LOUDLY* <jingle jingle jingle> (singing) When you get caught short,
don't be fraught, with BoneDryos.... Adult Diapers.....! <jingle jingle jingle>
Watch: The Guns'N'Roses concert in London is on...
<beep beep> Need Faster Broadband? say YES now! <beep beep>
... 16th of June 2017.
User: Watch, Great! I'll have two tickets please!
Watch: Hi, I'm about to buy you 'two tickets' for Gun'N'Roses Not In This Lifetime
Tour in London, at the London Stadium on the 16th June 2017 at 3pm but first,
here's a short promotion... <jingle jingle jing..
User: Oh, FFS...
As history has shown, once anything useful reaches critical mass, the Marketing Sharks and Money Men take it over to a level of un-usability.
