This watch communicates with an Android smartphone via a free app. You won't be reading emails on its monochrome screen, thank God, but it is a surprisingly great method for getting notifications. When you get a call, your watch beeps and flashes the name of the person calling. Ditto for text messages and emails. In testing, I found that it worked perfectly--the call showed up instantaneously on the watch, and would definitely reduce the number of calls missed because a phone is buried in a bag or accidentally set to vibrate.
