The Centenary Clock of Lier and the Wonder Clock
In Lier Belgium the Centenary Clock, noted for lavish astronomical features, uses 70 gears to depict time tides earth rotation and planetary orbits while showing solar and lunar cycles and astronomical constants. Its portable sister clock, the Wonder Clock, displayed at the 1938 New York World’s Fair, features 93 gears and 14 figures including ages of man maidens and a weight-checking youth, illustrating gravity across planets.
