All I really want out of a watch is that, plus long battery life (weeks at least, months preferably), self-charging, self-time setting, and, if I am lucky, some sort of "hey look at your phone" alert.
I get most of these with the Fossil Q. Others with my Citizens and Seiko non-smart watches, one of which has an e-ink display. Nothing has them all. Oh well.
I wonder if Google will make a Fossil Q which has it all. I do not need a display, health monitoring, etc.
