When your watch starts to lose time because it needs to be wound, or because the battery is dying, you’re going to be late for a bunch of meetings and family functions. It could have been avoided if you had a watch that runs on wind energy. Just blow at your watch and it will display the accurate time . This watch uses wind to produce just enough energy to display the time, and then the screen goes dark, but the watch keeps keeping time for you. You might look silly blowing into your watch, but who cares? It keeps time and it looks awesome.
