We have seen all sorts of smart wristwatches in the past years, and after seeing watches that can check your text messages and missed calls, we have a watch that can check your BAC (Blood Alcohol Level). This watch is designed by Tokyoflash, but so far, it’s just a concept. Despite that, this watch looks fantastic, but the best thing about it is that it can check your Blood Alcohol Level instantly.All that you have to do to check your alcohol level is to remove the side cap and blow into your watch. In order to see the results better, display is always on and it comes with multicolored backlight that is triggered by the touch-sensitive lamp button. After that, this watch will display how unconscious you are on the screen so you can easily keep track on your alcohol level.
