This is an English pair cased pocket watch, with a gilt inner and underpainted shell outer case, in good working condition. It has a high quality verge escapement fusee movement and was made around 1790 by Cosher (possibly Thomas) in Tottenham, London.
MOVEMENT : Nicely gilded movement, with round pillars, beautifully engraved balance cock with diamond endstone, blued screws and unusually, a five spoke polished steel balance wheel. The movement is signed and numbered (1293). The movement, with these high quality features, is in very good condition and is running well.
DIAL : The white enamel dial is about 41 mm in diameter and in fine condition with just one short hairline running from the edge at 5 towards 4. Unusual fleur de lys markers on the quarter hours. Nice matching gold coloured hands.
INNER CASE : Maker’s mark IG. The gilding is in good condition except for some wear around the outer edge and to the bow and pendant. The case is in good condition with no repairs.
OUTER CASE : This beautiful case is of underpainted shell over gilded brass.
The shell is in good condition with just some damage around the opening catch (see photo). Otherwise just a couple of small chips on the bezel. The painting, with gilt highlights, is beautifully done and has retained the bright colours. No repairs.
Loomes lists a Thomas Cosher in London in 1799. This watch is a little earlier.
