In 1947, Nathan Horwitt designed a wristwatch with a plain black face without numerals and a white disk marking the 12 o-clock position. The following year, his design was produced, without credit or compensation, by Zenith Movado. It was a prime example of design piracy, and Horwitt sued, but justice would take 27 years. In the meantime, the design was placed in the permanent collection of the Museum of Modern Art in 1960, and become known as "The Museum Watch.".
