So popular was the idea in the 1970s of a watch that ended what Harlan called the "dictatorship of exact time", that rock stars, doyens of art and theatre, movie stars and other members of the social elite purchased them. Harlan's Chronomachrons were worn amongst others by Mick Jagger, Ringo Star, Max Bill, Charles Aznavour, Carlo Levi and even by members of Iron Butterlywho wrote the Chromachron song!
