Wouldn’t it be great to feel powerful, at least as far as your gadgets are concerned? The Eole watch is a timepiece designed by Julien Moise that works under the user’s own breath power. The delicate rotating bit moves with nothing more than a gentle puff of air from the wearer’s lungs.

While the watch’s parts are sitting still the display is blank. But when the wearer exhales, the tiny rotor turns and enough electricity is generated to turn on the delicate-looking display for a moment, giving you just enough time to see whether you’re late for that appointment.

The watch’s display even features a little timer that lets you know how long the display will be visible before it fades away again. The ultra-minimalist design is not only lovely, but saves the problem of paying way too much for a watch repair shop to replace your battery.
