The well-known surrealist piece introduced the image of the soft melting pocket watch. It epitomizes Dalí’s theory of “softness” and “hardness”, which was central to his thinking at the time. As Dawn Adès wrote, “The soft watches are an unconscious symbol of the relativity of space and time, a Surrealist meditation on the collapse of our notions of a fixed cosmic order”. This interpretation suggests that Dalí was incorporating an understanding of the world introduced by Albert Einstein’s theory of special relativity. Asked by Ilya Prigogine whether this was in fact the case, Dalí replied that the soft watches were not inspired by the theory of relativity, but by the surrealist perception of a Camembert melting in the sun.
