In 1927, the National Geographic Society commissioned famed American painter N. C. Wyeth to create a series of murals to adorn the walls of its Washington, D.C., headquarters. The face of this large clock is a reproduction of the Western Hemisphere mural from our private art collection. Traditionally styled and always accurate, the clock synchronizes each night to the U.S. atomic clock in Colorado and self-adjusts for daylight saving time, leap seconds, and other time changes.
