A fine quality George III eight day
domestic regulator longcase clock by John & Miles
Brockbank of London c.1790
The Brockbank
brothers John (1747–1806) and Miles (1754–1821) were
born in the remote Cumbrian parish of Corney, trained as
watchmakers in London and formed a partnership in 1781.
The dominant figure in the partnership was John, the
elder brother. Miles is mainly notable for his
invisibility. Their close acquaintance with both
John Arnold and their employee Thomas Earnshaw
inevitably drew their attention to chronometer
production. Chronometers became the focus of the
business from 1788. The brothers’ main interest was in
production rather than
invention, and they succeeded in building the largest
chronometer manufacturing business in the City. When
John died his estate can be roughly valued at
£12,000, equivalent to £850,000 today. Miles
probably accumulated a similar amount.
