A fine late Georgian pocket chronometer, almost certainly by Pennington.
Large silver case hallmarked London 1818, casemaker Y/HG (probably Henry Galloway, Clerkenwell, but the addition of the Y is not at present understood). Fullplate fusee movement finished in the then fashionably plain style, with cap jewels on balance (diamond) and escape, the distinctive escape hole shape a sign of the work of Robert Pennington, or someone trained by him. Chronometer escapement, the spring-detent of Pennington's dovetail footed design. Compensation balance of somewhat unusual form, with Earnshaw-style wedge weights plus the addition of quarter-timing screws, the outer rims with engraved scale. 6-turn blued-steel helical spring with Arnold's terminal curves. Signed enamel dial in perfect condition, blued steel hands. Together with lovely 3-piece mahogany deck box, the Patent lock retaining its original keys - two of them. Most unusual. Watch 56 mm diameter, box 11 x 9 x 6.5 cm.
