I quit wearing a watch years ago. My car has clock, my computer has a clock, my phone has a clock, my stove has a clock, my TV has a clock, and every work environment has a big clock on the wall. I am never without my phone and it has notifications, so why wear a watch?
I just don't see the need until the watch can replace my phone and I don't see that happening with the current state of technology. Plus if the current phone innovations are the indication of a trend, then the watch that replaces my iPhone will only be available in 6 or 7 inch screen.
