UK's Gadget shop Boystuff has two new wristwatches that display time in the binary code with LED diodes.
The round Binary LED watch features a face plate where the circuitry is visible. The square binary LED watch (see photo below) has the LED lights on a solid face plate. For both watches the time is shown in two LED rows. 4 LEDs show the hours and 6 LEDs show the minutes. If you know binary code reading time is easy. To make it a bit simpler the values of the LED positions are printed on the dial.
