Pocket chronometer movement, silver case, hall-marked 1825, by Earnshaw; London, England, 1825; dia. 2” (5.08cm.).
This is another example by Earnshaw, made near the end of his career (d. 1829). There are no wires for restraining the weights on the rim of the balance. Only the balance cock bears decoration and that is in the form of engraving. Pierced work was much less popular at this period, and when seen is usually on verge watches that were more traditional in design than those with the new precision escapements.
