Power Watchz Micro Racer Infrared Control 2003 With Batteries.

There are two buttons on the right corners with arrows showing on them, but these are for the extra attachment on the strap - a remote control car! Once the car has been taken off the strap, and the power buttons on car and watch have been turned on, you have a fully working remote control car. The buttons on the watch move the car forwards or backwards while turning (and it goes at quite a speed). At the bottom of the watch, there is a select button which sets one of 4 channels, so you can race with up to 4 friends at the same time. One site I found stated that this was the World's Smallest Watch Controlled Car!
