The Japanese watch company Tokyoflash has long turned heads with their odd (if unreadable) designs but in a first they’ve added a breathalyzer to their Kisai watch, thereby allowing you to see just how drunk you’ve gotten at la Jetée. The video below is a bit, shall we say, obvious: the company hired a charming Scottish man to get drunk. He, in turn, does. He then tests the watch, showing off its various features. In short, the watch has a sobriety game – basically a little test of your hand eye coordination – as well as a real breathalyzer built in. While the readings probably wouldn’t hold up in court, it’s accurate enough for you and your drunk friends. Given the problems I could see associated with passing your watch around so people can blow directly into it, you may want to buy a few for your entire gang.
