This watch was once the property of Sir Robert Williams II (1767-1847), a financier in London; he was Alderman and Sheriff of London in 1796/1797, as well as Member of Parliament and Magistrate and Deputy Lieutenant for Dorset. In 1814 Williams inherited Bridehead Estate in Dorset from his father.
King George IV believed Robert to be 'a most respectable loyal man, and always supporting the king's government'.
The case maker William Mean , who produced this case, worked in 1817 - when this watch was made - at 19 St. John Lane. His first mark was registered on April 9, 1783 at 8 St. John’s Street Road; the next one followed on August 15, 1791 at 7 Albemarle Street, St. John Square. There was another one at 19 St. John Lane on August 2, 1799 and a later one at 2 Jerusalem Passage on December 1, 1818. All these addresses were located in close vicinity of each other in eastern Clerkenwell.
This was the signature the brothers John and Myles Brockbank of London used for their watches, which were usually excellent pocket and marine chronometers. The brothers were outstanding early chronometer makers and members of the Clockmakers' Company. At times they worked with such prominent makers as Thomas Earnshaw and Peto, who developed a variant of the spring detent escapement - the "cross detent". Some of the existing Brockbank chronometers are fitted with this type of escapement and fetch high collector’s prices on the market today. Between 1775 and 1815 the Brockbank brothers took Samuel Elliot Atkins as a partner and the company began trading under the name of Brockbank & Atkins.
