John Ellicott (1706-1772) was one of the most important English watchmakers and inventors. He was watchmaker of the King and “Fellow of Royal Society”. As is the case with other major English watchmakers such as Tompion or Graham, it often happened that these valuable movements were given a new case in the 19th century, when the original, mostly golden case was broken or missing.
