Binary watch the ultimate in geek-wear

The LED Binary Watch from Time Technology: Could there be a more perfect IT guy accessory?

When it comes to the math crowd, watches with simple hands are so 2004. This gadget displays the time using the numbers of the binary sequence (1, 2, 4, 8, 16 and so on). The values of the lighted LEDs are added to determine the time; add the top LEDs to get the hour and the bottom ones for minutes.

This might sound like a lot of work to find out the time, but one blogger who favorably reviewed the product said telling time using binary isn't all that complex. "All one really needs is a basic ability to do mental arithmetic," he writes.

The water-resistant watch comes with a soft leather band, a futuristic-looking circuit board watch face and a stainless steel back and casing. The product, which comes with batteries, is available for $69.99 at ThinkGeek.
