If reading a conventional watch isn't exciting enough for you then I suggest you check out the Yonkaku Watch. The Yonkaku Watch, created by a one-name designer known as Sam, uses a grid divided into nine squares to tell time.
Squares of different sizes pop up within the nine squares to help you tell exactly what time it is. The design of the Yonkaku Watch is a little confusing, but I'm sure it's nothing that an instruction manual can't explain. Ball's in your court, Tokyoflash.
