technological advances during the 18th century saw the introduction of the cylinder escapement and the spring detent escapement by Arnold and Earnshaw with a bimetallic compensation balance, but the lever escapement developed by Thomas Mudge proved to be the most valuable asset to the watch-making industry of the time.
He was the only watchmaker ever to have received a CBE and an MBE for his services to horology and the inventor of the revolutionary Daniels "coaxial escapement", the first new watch mechanism created since the invention of the lever escapement by Thomas Mudge in 1754.
