The 18th century proved to be a crucial period in this evolution as the cylinder escapement was introduced, revolutionizing timekeeping accuracy. The cylinder escapement is a type of escapement that uses a cylinder-shaped roller instead of the traditional lever escapement. It enabled pocket watches to keep accurate time for longer periods by reducing friction and wear on the watch’s mechanical components. The cylinder escapement was a key step in the development of modern pocket watch movements that allowed watchmakers to produce more precise and reliable timepieces, making them more widely available to the general public.
4. In the 19th century, the lever escapement was introduced, which is still used in modern pocket watches.
The 19th century marked a significant milestone in the evolution of pocket watch movements with the introduction of the lever escapement, which is still used in modern pocket watches. Prior to this, older designs such as the verge and fusee movements were widely used. The lever escapement was developed by Thomas Mudge in 1755 and was refined over the years until it became the standard for accuracy and reliability in watchmaking. This new design reduced the friction and enhanced the accuracy of the timepiece. Its primary components included a pallet fork, which engaged with the escapement wheel, which in turn controlled the balance wheel. Even after the introduction of the quartz movement in the 20th century, many pocket watch enthusiasts still prize the classic lever escapement for its historical and traditional value.
5. The 19th century also saw the introduction of the Swiss Anchor Escapement, which was widely adopted.
The pocket watch movements began to evolve rapidly in the 19th century.
