If you like to go out and have a drink, it’s always problematic when you have to decide whether to drive your own car back home. Sometimes, enough time has passed for you to no longer be intoxicated, but other times, you’ll end up with a DUI – or worse. This watch could save your life.

The Tokyoflash Kisai Intoxicated has a built-in breathalyzer, which will test you blood alcohol level with its sensor. You’ll need to blow into the side of the watch for five seconds and wait for the watch to give a reading. The watch shows 10 different levels of blood alcohol content.


Green means you’re stone cold sober. Yellow means your BAC is between 0.41 and 0.60%, meaning you’re slightly buzzing. A red display shows 0.61% and more, meaning you’re drunk, and .80% or higher means you’re legally drunk in most places. Keep in mind that Tokyoflash doesn’t warrant that the results are completely accurate, so officially the watch is “for entertainment purposes only.”

There’s even a built-in sobriety game to test your reactions. It involves hitting a line when its in the dead center the screen. The game is harder when you’re not sober.

The Kisai Intoxicated watch is currently available for pre-order for a special price of $99(USD) for the rest of the day today. On 6/21, it will revert to normal retail price. Tokyoflash expects to deliver pre-ordered watches by July 8th.
