Good large rack lever movement with 15-seconds dial, circa 1810.
Capped fullplate fusee movement with balance-brake, the escape wheel set in slides and Roskell's usual sighting holes in the plates, used to help establish optimum train depths. Litherland's rack lever escapement with 30-tooth escape. Steel balance, spiral balance-spring. Original one-piece enamel dial with 15 seconds indication at 6, gold hands. 51 mm diameter, 13.5 mm deep, not including centre arbor.
Robert Roskell, famous Liverpool watch, clock and chronometer maker, one of the most influential of Lancashire watch manufacturers who soon overtook the output of Litherland himself.
Peter Litherland, Mount Pleasant, Liverpool. PATENT No 1889, June 1792. A form of non-detached lever escapement that was successful not only for him and his partners but also gave rise to what soon became a burgeoning Liverpool watchmaking industry and its exports to America.
Edge chips to dial and hour hand with repair. Otherwise complete and unbroken, but ticking slightly out of beat and will not continue to run if wound. A well finished and unusually large example of a 15-seconds rack, but sold as needing at least a service to run properly.
