C.1810, James Hatton, London, 8-Day Marine Chronometer, serial No. 444, double frame movement with reverse fusee, Harrison's ratchet and Earnshaw type spring detent escapement, a large seconds dial with Arabic 10 second figures, and with up-down indication to 7+ days. Condition: the mahogany case has been refinished. The movement, dial and gimbals are all in good condition; the bezel appears old, but has had 3 lumps of solder put on the inside in place of a tension ring, and this should be attended to. Movement is running crisply; it appears that 2 or more screws have been added to the compensated balance. Diameter of dial = 4.8"
