What is it?

How does it work? Switch it on to camera mode, tilt it so the screen picks up the image, and click. Or take it off your arm, point and shoot.

And then? It gets more fiddly: plug it into your PC, put in a CD, which holds the software, download the image, and get it on screen.

Image quality? Not as good as a "real" photograph: it's only got 28,000 pixels compared to about three million in a top digital camera. But it holds a hundred images.

Black and white only? 'Fraid so. Just daylight use - no flash.

Weighs a ton? More than the average watch, but nothing like those frying pans that diver's wear.

Who makes them? Only Casio. They're also bringing out an MP3 watch: 33 minutes of CD quality sound, or one hour of FM quality.

Prices, please? The wrist camera, in the shops on August 1, costs £179.99; £299 for the MP3 watch. Call 020-8450 9131 for stockists.
