Rare rough movement, circa 1880.
Three-quarter plate keyless movement ready to be 'scaped and finished, the hollow-back pillar plate stamped JP and with its Liverpool size 16 x 4 (4 being the distance between the plates).The frame and cocks not yet fully drilled ready for the train to be fitted, an earlier than usually seen stage in the process of manufacture, with cock but no escapement parts present. Movement 44.5 mm diameter.
Joseph Preston, Prescot, the most famous of Liverpool watch rough movement manufacturers, supplier to all the best English finishers and retailers of his day.
NB: English watch manufacturing was split into at least forty separate specialist trades at this time, around 50% who were involved in the manufacture of rough movements, which the Swiss/French called an ebauche. It is easy to see how much work was still needed at this point, but also to see how wonderfully good and crisp was the work of these pre-eminent, mostly Prescot based, specialists.
An interesting and rare document regarding the English practice of making watches, no watch collection complete without such an example.
