When you are plastered into an oblivion time doesn't really matter, does it? So put your wristwatch to another use by determining precisely how sloshed you are. This cheap-looking wristwatch has an integrated breathalyzer—give it a little blow to see if you are legally sound to drive, or give it a blow to prove to your friends that you can indeed hit the .30 level and still remain conscious. It will be available later this month for around $100 from A&A Products of Hong Kong. – Travis Hudson
