In 1971, Swiss artist and architect Tian Harlan elaborates his Color-Time-Circle. He creates many objects and art projects based on this idea, among them a color-time plastic for the Olympic games in 1972 at Munich and a color-time-tower as high as 21 m. In the 80ties he started cooperation with Pierre Cardin on watch design and founded the CHROMACHRON AG in Switzerland to produce timepieces with a yet unknown time indication and philosophy.
