Brockbanks
A remarkable, very fine pair-cased pocket chronometer
Sold
The case maker William Mean, who produced this case, worked 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.
"Brockbanks" - 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.
