JB Joyce clock Whitchurch, at Liverpool Lime Street mainline railway station, Merseyside, England, UK, L1 1JD

J. B. Joyce & Co, clockmakers, were founded in Shropshire in England. The company claim to be the oldest clock manufacturer in the world, originally established in 1690, and have been part of the Smith of Derby Group since 1965. The claim is challenged by another English firm of clockmakers, Thwaites & Reed, who claim to have been in continuous manufacture since before 1740, with antecedents to 1610. William Joyce began in the North Shropshire village of Cockshutt making longcase clocks. The family business was handed down from father to son and in 1790 moved to High Street, Whitchurch, Shropshire. In 1834 Thomas Joyce made large clocks for local churches and public buildings. In 1849 the company copied the Big Ben escapement designed by Lord Grimthorpe. J. B. Joyce also installed synchronous electric clocks in a number of railway stations, including Liverpool's Lime Street Station, Aberystwyth in Wales, and Carnforth in Lancashire. In 1904 J. B. Joyce moved to Station Road, Whitchurch. John Edgar Howard Smith (1907–1983), a former managing director of Smith of Derby Group, designed the first and subsequent synchronous electric movements for J. B. Joyce, and their associated electro-mechanical bell striking units. In 1964, Norman Joyce, the last member of the Joyce family, retired and sold the company to Smith of Derby. During the 1970s, many of the mechanical clocks were changed to use the electric motors made by the Smith parent company.
