Traditional electronic watches may be practical, but there's nothing elegant about battery power. With the Eole watch concept, designer Julien Moise envisioned a device that's powered by blown air, displaying the time only when you want to see it. Sure, compulsively blowing on your watch in a meeting is less discreet than sneaking a peek under the table, but you'll still have your BlackBerry around for when you need to count down the minutes until freedom. There's also a weather indicator and alarm function, so we assume there's a battery in there that's doing more than keeping time -- an alarm that only sounds when you blow wouldn't work too well if you're asleep.
