You have to love the awesome complication of Tokyo Flash timepieces, for some of them you practically have to be a mathematician to figure out the time, which makes them completely impractical for most people, but a whole lot of fun.

In order to check the time on the Kisai Sensai, you first need to press the button on the side, then you count the LEDs: red LEDs display the hours, while green LEDs show groups of five minutes and yellows show single minutes. Once you are done calculating the time, a whole other minute will probably have passed.

Price: $260 [Tokyo Flash via CrunchGear]
