01 Binary makes binary watches. the upper row represents the hours and the lower row the minutes. Somehow I would have liked it even more if the numbers and hour text wasn't shown on the print, since I can read binary and with a little practice you can read the time easily. Specially if you realize that the bottom left and the next LED represent just a little more than 30 and 15 minutes. It only has a 12 hour system. It shows now 5:56. Due to the daylight I see, it will be P.M.
