The Liverpool watchmaking firm of Joseph Johnson operated from about 1800 to 1870. While not credited with any significant technical advances, the firm combined an unusually large volume of production (for the pre-machine age) with a high standard of finish. From about 1820 most of its products were exported to the United States. I have been interested in the house of Johnson since 2000 and currently own seven examples of their work. This database comprises nineteen pages and records 272 watches and movements.
