Though not quite the same as the
binary clock described above,
RSI Digital, based in
Norway, does offer a
binary watch. Starting at 25 US
dollars, you can confuse the hell out of your less-enlightened
cow-orkers. And they just plain look cool, even if you choose to leave the watch in its
base 10 display mode.
The watch's display, instead of having dots, simply has a ones-and-zeroes time, like this:
01101
001011
100000
Which, of course, translates to 13:11:32.
This version also incorporates the more mundane features most of us expect in a digital watch these days -- stopwatch, alarm, timer, and Indiglo-style backlighting that they can't call Indiglo because Timex probably trademarked the hell out of the name.
Refer to http://www.rsi-digital.com/ to buy one of these digital marvels for your own wrist. This is not a paid advertisement; I just think the one I bought is really neat.
