Thomas Earnshaw (1749-1829) He began his training in watchmaking in 1763 and, from 1780, produced watches for Brockbanks. Around 1781 he invented the spring detent escapement in his workshop, which would be used essentially universally for more than 150 years. In 1794/95, Earnshaw took over William Hughes’ company in High Holborn. For his enhancements of the escapement, Earnshaw is generally considered a pioneer in chronometer making. His company produced about 3000 pocket watches and about 1500 marine and pocket chronometers of the highest quality.
