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 had been Mudge's junior worker and had been dismissed, brought with him important technical knowledge. To reduce production costs, they decided to use a single balance spring and Arnold's "Z" balance with helical balance spring. The watch was apparently upgraded in 1818, at which time a new case was also made.
