30. The Empire Clock

30. S. Smith & Son, 1912
The Empire Clock
Smith Collection: SM-1912-27

World clock that would show the approximate time (based on mean solar noon) of any area around the globe. It would have to be wound every 16 days. The brass ball mounted on the arm can be moved around the globe or up and down the arm to demonstrate the changing positions of the sun. Additionally, the sun can supposedly follow the ecliptic line on the globe if it is turned one full rotation every day, but it wasn’t exact and could only be used as a demonstrational instrument, not a scientific one.
