Provenance: The Selwyn Demmy Collection. Arnold and Lewis were makers and retailers of high quality watches, clocks and chronometers who succeeded I. Simmons at 7 St. Ann's Square Manchester in 1871 where they remained until 1905. In July 1872 they installed a shop regulator with a galvinometer connected to Greenwich at their premises (designed by Edward Salomons architect) incorporating an exterior clock dial with a Greenwich style falling ball dropping at 1pm daily. This was reported in the Manchester Guardian, and no doubt provided endless publicity for the new proprietors. The current lot would appear to be that very regulator as it is fitted with a galvanometer which would be receive an electrical impulse from Greenwich every hour causing the needle to 'flick' exactly on the hour. As the 'shop regulator' the present timepiece would have served to set and check the time of watches in the showroom as well provide accurate 'Greenwich Mean Time' to the public.
