Chromachron 1971 Tian Harlan Design handwind

Unique design watch which was created in 1971 by architect, engineer and artist Tian Harlan. It tells time by the different colors, hence the name “Chromachron” (Chroma=Color, Chronos=Time), as found on the back. It also states “Pat.Pend”  which stands for Patent Pending, which leads me to believe this is one of the very early models, before the patent was recognized and before the edition with the Tian Harlan name were released. The case of this chromachron 1971 wath is a lightweight acrylic round shape measuring 39,5mm without the original shiny chromium plated crown. The ring around the black acrylic front is also chromium plated. Hardly signs of wear or use.

The Chromachron 1971 was meant as a relaxing watch that did not tell time exactly. The central black rotating disk has a triangle cut out and turns over the 12 different colored time zones (1 color per hour). It moves continuous and when an entire color is shown, it would be exactly X 0′ clock all other time intervals need to be ‘guessed’ more or less. It has a quality well working swiss handwind movement. I put the watch on a period design steel bracelet that will fit a wrist up to 19cm. A normal strap can be attached as well. No box. no papers.
