'Empire' type world clock for indicating the time around the globe at various longitudes with accessories, France, 1909. Patented by Etienne de Gounevitch and Armand Gustave Couailett (British patent No. 23, 449, 1909).

This clock is designed in the form of a globe, and driven by a clockwork motor to make a full rotation from west to east every 24 hours. By following longitudinal lines, it is possible to tell the time at any given point on the globe. A brass ball can be attached to indicate the sun. It was called an Empire clock because it enabled the time in all the countries of the British Empire to be checked at a glance.
