In 1761 John Brookbank established a clock manufactory in London together with his brother Myles. Both brothers were members of the Clockmakers Company and had a reputation as makers of excellent chronometers. Thomas Earnshaw and Peto both worked for the Brockbanks brothers from time to time. Sometime between 1775 and 1815 John and Myles Brockbanks took Samuel Elliot Atkins into their company and began signing their watches "Brockbanks & Atkins".
