Pin-pallet escapement
Mechanical watch component
A Roskopf, pin-lever, or pin-pallet escapement is an inexpensive, less accurate version of the lever escapement, used in mechanical alarm clocks, kitchen timers, mantel clocks and, until the 1970s, cheap watches now known as pin lever watches. It was popularized by German watchmaker Georges Frederic Roskopf in its "proletarian watch" from 1867. It was invented in 1798 by Louis Perron, of Besançon, and suggested to Roskopf by Jules Grossmann.
