Edward East was one of the founding members of the Clockmakers’ Company and served as Master in 1645 and again in 1652. He was appointed Clockmaker to both King Charles I and Charles II and was known for crafting high-quality watches and clocks. His timepieces were often used by the King as prizes in tennis matches, a testament to their esteemed quality. East also created night clocks, featuring revolving chapter rings with perforated numerals illuminated by a lamp to display the time. His craftsmanship was highly regarded, and he continued to influence English clockmaking throughout his life.
