The probably most famous clock of the world, called also amount apprenticeship-clock, invented by Mr. Dieter Binninger in the 70s. It was built for the town of Berlin and stood from 1975 to 1995 in Berlin in Kurfürstendamm. Today the original stands in Berlin in the European centre. The Berlin clock indicates the time on the basis of light symbols: The First line - lamp five hours. the second line - lamp one hour. The third line - lamp five minutes, every third lamp is red to the better recognition of the quarters of an hour. The fourth line, lamp one minute. Already after a short time one has got used to this unusual time announcement and can read the time like in a normal clock. A cult property, must for every Berliner.
A sensation is the Berlin timer. The time can be read not only easily and well, but also hired.
Thus the desired time can be chosen very fast and very simply. A loud Beep sounds at the end of the timer.
