The Nelson Polygon Clock (1961) is one of more than 150 clocks designed by George Nelson Associates for the Howard Miller Clock Company, which sold them from 1949 into the 1980s. Nelson Associates employed some of the most celebrated designers of the time, including Irving Harper, Don Chadwick, and John Pile, all of whom contributed to the clocks. Today, the Polygon Clock is produced by Vitra Design Museum. Uses one AA battery (included). Made in Poland.
