Breathalyzer Watch Measures Intoxication, Gives B.A.C Readout

Japanese watchmaker Tokyoflash has just introduced – and sold out of – a watch that measures just how drunk its wearer may be. The breathalyzer-enabled Kisai Intoxicated is a limited series wearable from Tokyoflash that keeps tabs on users’ levels of intoxication.

The watch is actually a bit of a marvel, given how well it’s been optimized for drunken (ab)use. The sturdy, stainless steel band/case seem durable enough to take a beating, and they house an extra-large screen with backlit, negative space LED numbers. The time is always brightly visible on the watch’s screen, meaning users don’t have to fiddle with the display to check the time.

Also, the watch measures inebriation by two metrics: the first is a classic breathalyzer, the second an interactive sobriety game. Blood alcohol content is measured and then a colored readout  is given based on its findings. A green screen means a user is buzzed (.01-.4 percent BAC), yellow means slightly imbibed (.41-.6 percent) and red says drunk (.61-1.4 percent). Each color is as vivid as the LED screen will allow, making reading simple for cross-eyed boozers squinting in the dark.

The sobriety game tests hand-eye coordination via the watch’s retractable dial. Users are meant to time their reactions against the watch, which registers and ranks reflexes, then guesses at how drunk you may be.

To showcase the Intoxicated, Tokyoflash found a hardy Scot, slapped the watch on his wrist and began pouring him beer. They recorded him testing the breathalyzer, the game, and the watch’s durability and then posted their results to the watch’s page.

Kisai Intoxicated promises to be a fun party game, but the company dismisses legal liability with a typical disclaimer: intoxication laws vary by government, never drive drunk, etc. And while we wouldn’t recommend using the watch to test whether or not you can legally drive home, we do suggest you get one (if you can) to pass around with friends as a game.
