A minimalist-style black and white metal battery-operated clock called the "Museum Wall Clock" has a black face, white hands, no numbers and a simple white circle at 12 o'clock. The white circle symbolizes a sundial, an homage to the ancient form of timekeeping.
Designed by industrial designer, Nathan George Horwitt, the Museum Watch was his best known design. Originally designed as a watch in 1947, it was produced in large numbers especially by the watch company Movado. By 1960 this wall version was being produced by Howard Miller Clock Company and was incorporated into the permanent collection of the Museum of Modern Art, NY.
