Between Messed-up Monday, Trashed Tuesday, Wasted Wednesday, Thirsty Thursday, and, of course, the weekend, sometimes it hard to keep on schedule and your drinking in check. While it is certainly no replacement for responsible drinking and having a DD, the Kisai Breathalyzer Watch has a built-in breathalyzer that can test your blood alcohol level with its sensor. Oh, and it tells the time. Whether you use it as a gag gift or as a way to really test your tolerance, you just blow into the side of the watch for five seconds and wait for the watch to give you a reading from among the ten different levels. There's even a built-in sobriety game to test your reactions that sounds hard enough even if you haven't been hanging out with Jim or Jose. The Kisai watch is currently available for pre-order for a special price of $99 for the rest of June 20. On June 21st, it will revert to normal retail price. Tokyoflash expects to deliver pre-ordered watches by July 8th.
