Apple unveils its version of the smartwatch.
FOX News Radio's Jessica Rosenthal reports:
Apple is billing its new watch as essentially being able to do a lot of what your iPhone can do. Apple CEO Tim Cook says it can send and receive messages.
(Cook) "You can also -- with a built in speaker and microphone -- you can receive calls on your watch. I have been wanting to do this since I was five years old."
It's heavy on health and fitness -- it tracks your heart beat. It even alerts you if you've been sitting too long.
Apple Pay is on it as well. And Cook says battery life is supposed to last 18 hours each day.
The sport version starts at $349. The main version at $549.
