Originally fitted with a cylinder escapement, this watch was later upgraded to include an English lateral lever escapement with pointed tooth escape wheel and jeweled pallets.This watch is published in the Ruscitti book, as no. 37.Mudge, Thomas (1715-1794)was an apprentice of George Graham and may be considered his spiritual successor. He constructed an hour-striking watch with minute-repeating and equation of time display for the King of Spain. He was one of the first makers to produce constant force watches. His ordinary watches with cylinder escapements are constructed on the same general lines as those of Graham. In 1755 he went into partnership with William Dutton, another of Graham's pupils. In the 1760's he developed the free lever escapemnt. With Larcum Kendall he was nominated in 1765 to examine Harrison's marine watch. In 1770, after much difficulty, he succeeded in making the first lever escapement for watches. The watch was purchased by George III and is still in the Royal Collection. In 1771 he retired to Plymouth where he devoted himself entirely to research on marine chronometers. It is there that he developed his constant force marine watch described by his son in a publication of 1799. He was also the inventor of a freeescapement with remontoir, of which the principle was published in the Philosophical Transactions of 1794.
