No Swiss watch can beat an Apple iDevice for accurate time, as long as it has internet access. It also automatically switches time zones and between daylight savings time and standard.
If the iWatch syncs to one's iDevice, then it will also have such accuracy and be back on one's wrist for convenient access.
We haven't yet seen everything else that it will access and make more convenient, but, just like the computer is a "general purpose machine" thanks to its programmability and digital inner workings, the iWatch will be not just a watch and certainly far more general purpose than an analog set of revolving "hands."
I think the Swiss watch industry is truly in for a rude awakening in the not-too-distant future.
Doubt it. Let me know when the "iWatch' has enough battery power to last for several days and can be considered useful as survival gear as well. You know - where or when there's no power source for several days to recharge?
