This clock has a slim body and easy-to-read minimal design. Each "blade" of the Monochrome Wall Clock is a different shade, a progression of light to dark that suggests the passage of morning to night. The hour markers progress from dark to light as time passes. The Monochrome Wall Clock reflects the Museum's long history of documenting and displaying timepieces from the modern era, many examples of which are featured in the Museum's collection. One AA battery and hanging hardware included.
