A $100 Watch Can Tell If You've Had Too Much To Drink

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.

The display on the right of the screen shows 10 different levels of blood alcohol content. A green display showing 0.00‰ means you’re sober. A yellow display showing between 0.41 and 0.60‰ means you’re buzzing. A red display showing 0.61‰ or above means you’re drunk!

The watch costs $99 and charges via USB. Thankfully the face is actually readable so it should be a snap to check in every few hours for a round of “Who had more Kirin?” at your local watering hole.
