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.
