More details

Silver barrel-edge case with gold joints hallmarked London 1826, casemaker ID (probably James Dow, Clerkenwell)). Fullplate fusee movement with beautifully engraved cock and barrel-bar, 5-wheel train and cap jewels on balance (diamond), and escape. Pennington's form of dovetail-footed spring-detent escapement and compensation balance, with 6-turn blued-steel helical balance-spring. One-piece signed enamel dial, original gold hands. 60.5 mm diameter.

Santiago James Moore French, Sweetings Alley, Royal Exchange, London, a fine watch and chronometer maker with examples of his work in most Museum collections around the world. 

NB. Few English 8-day pocket chronometers are known most of which are by Margetts. Though in a watch style case, these are too large for wearing as a pocket watch. This example by French is just one of three known English pocket sized chronometers. One, by Parkinson & Frodsham, survives as a recased movement. The other, a Nicole Nielsen item retailed by the firm of Charles Frodsham, is 72 mm diameter, which I regard as too large to be used as a pocket watch. At just over 60 mm, this example, probably supplied by the Pennington firm, can be safely worn.

Slight hair cracks to the dial edges at 3 and 8, otherwise in wonderful original condition looking to have been hardly worn - an exceptional English chronometer. Cleaned, guaranteed and supplied with a properly fitting key.
