Charles Hutton Errington, Coventry, Patent No 5639, December 1881 - an improved method of stopping and starting keyless and other centre-seconds watches via the pendant. Later bought by H Williamson, the Coventry firm of Errington was one of the first successful machine-made watch manufacturers in the UK.
Joseph Reuben Vickers & Co, watchmakers.
A rarely encountered Patent movement, more highly jewelled than most pocket chronometers. Lacking two of three dial feet, otherwise in very good original condition. Not cleaned by me but will tick if wound.
