Thomas Mudge, inventor of the lever escapement. The lever escapement, invented by Thomas Mudge in 1754 [18] and improved by Josiah Emery in 1785, gradually came into use from about 1800 onwards, chiefly in Britain; it was also adopted by Abraham-Louis Breguet, but Swiss watchmakers (who by now were the chief suppliers of watches to most of Europe) mostly adhered to the cylinder until the 1860s.

This type of watch winds itself without requiring any special action by the wearer.
