Thomas Mudge, technically and historically significant astronomical movement with double dial, equation, annual calendar, central second, and repeater, ca. 1750.

D 53.5 mm.

This exceptional movement could be a special order for the King of Spain. This was probably the first time that a complete display of the equation of time was realized, using a separate dial with hour- and minute hands, on a portable watch. In order to achieve this, Thomas Mudge used both a worm gear and a differential gear.
Thomas Mudge was one of the most important watchmakers of his time. He is also considered the inventor of the lever escapement, from which almost all modern wristwatch escapements were developed.
