"The Berlin-Uhr is a registered trademark by D. Binninger who invented it in the seventies. It was originally installed in 1975 at the Kurfrstendamm in Berlin. Due to technical problems and the running costs of roughly 5000 Euro the clock was switched off in 1995. One year later the clock was reinstalled close to the Europa Center in front of the tourist information and is presently sponsored by merchants within the Europa Center. The Berlin-Uhr is based on the principles of quantity didactics and with this its the first of its kind. The time is calculated by adding the lit rectangular lamps. The top lamp is blinking in the rhythm of the seconds. The upper row of four lamps represents 5 hours each. The four lamps in the row below indicate one full hour each. Three burning lamps in the first row and two in the second account for (5+5+5+1+1+1) 18 hours, which is 6pm. The third row of eleven tall lamps represent 5 minutes. In the last row every lamp represents 1 minute."
