Motorola has had a Droid watch out for a while, now. My moto X is made in America, 1/2 the thickness as my mother’s iphone, with a bigger screen and a longer battery life. Apple is just responding to stuff already in the Android market.
Battery life not addressed at unveiling.
Best competitor watches with B&W screen last 3-4 days, all other competitor color screens are lucky to get 1 day.
Sounds like being plugged in is a way of life!
