Historical context
The pin-pallet escapement, also known as the pin-lever or Roskopf escapement, was invented in 1798 by Louis Perron of Besançon. Suggested to German watchmaker Georges Frederic Roskopf by Jules Grossmann, it was popularized by Roskopf in his 1867 "proletarian watch". This mechanism served as an inexpensive version of the lever escapement widely used in cheap watches.
