Fleur-Ange Lamothe

Congreve Rolling Ball Timepiece - circa 1810

The steel ball takes 30 seconds to roll from one end of table to the other; at each end, a catch is released, enabling the spring-driven movement to tip the table the other way. Mainspring requires winding at 21-day intervals. It has been estimated that the ball travels ~ 2500miles a year.
