Early pocket chronometer with silver case by the firm of Barraud of Cornhill;
For extra legibility there are two subsidiary dials for hours and seconds leaving only the minutes on the main dial. The seconds dial has each fourth division numbered, a feature which was not perpetuated. This chronometer was worn for over a year in 1962/63 and performed very well although it dates from 1797. The escapement is of the Arnold type which differs from the Earnshaw (c below). The bow (hanging loop) and the case hinge are characteristic of the period as is the legibility of the dial.
