Watches are meant to put function first—you know, tell time, then, maybe, look sharp. The TokyoFlash team doesn’t subscribe to that philosophy. Past concepts included impossible-to-read dials with bingo-style layouts, neon light bars, and even, traffic-pattern LEDs. Their latest might be their most useless—or useful, depending on whom you ask—creation yet: the breathalyzer watch.
It’s rather simple to use, as the video above demonstrates: just hit the cocktail logo to rev the breathalyzer and then blow into the small tube, and wait as the dial reads back your BAC to you in a matter of seconds. Why not get one if you’re prone to the occasional DUI?
