Too drunk to drive? Your watch can tell!
Engineers have developed a new watch, with a built-in breathalyser, that warns you when you're too drunk to drive.
The Kisai Intoxicated's sensor is made from stainless steel and features an LCD display.
It reads the alcohol level in your breath and judges if you're too tipsy to climb behind the wheel.
Users have to simply blow into the side of the watch after boozing and the screen turns red if they're over the limit.
"The display on the right of the screen shows 10 different levels of blood alcohol content. A green display showing 0.00 percent means you're sober. A yellow display showing between 0.41 and 0.60 percent means you're buzzing. A red display showing 0.61 percent or above means you're drunk," according to TokyoFlash, the Japanese makers of the watch.
The snazzy-looking digital watch even features a sobriety game that lets you test your reaction time between drinks, The Sun reported.
The gadget will cost 65 pounds. It uses a rechargeable battery which takes 3 hours to charge. Based on average use of the breathalyser, the battery should last for one month on one charge and has a lifetime of over 300 charges.
As well as an integrated breathalyser, the watch has date, time and also an alarm mode.
