Eole concept watch has turbine bezel, shows time when you blow (video)

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 discrete than sneaking a peak 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.
