Notes

Provenance: Time Museum, Rockford, Illinois, illustrated and described in their catalogue by Anthony G. Randall, pp. 70-71. Paul Philip Barraud An eminent British maker, in 1796 he entered into partnership with William Howells and George Jamison, to make chronometers based on Mudge?s original design. Howells, who used to be Mudge?s junior worker and had been dismissed, brought important technical knowledge to Barraud. To reduce the cost, they decided to use a single balance spring and Arnold?s ?Z? balance with helical balance spring. The watch apparently was upgraded in 1818 when a new case was also made.
