He was one of the outstanding clockmakers of the 18th century, producing a large number of high quality clocks for the home market and export, his work particularly valued by the Spanish Royal family. He developed his own temperaturepensated pendulum and was instrumental in the perfection of the cylinder escapement. He was clockmaker to King George III, a position which paid 150 per annum. He was elected a fellow of the Royal Society on the 26th October 1738 and published articles on clocks and an equation of time table in the Philosophical Transactions for the Society.
