'Cylinder escapement 'dumb repeater' watch by Conyers Dunlop, with enamelled gold case signed by George Michael Moser, made for Queen Charlotte (1744-1818).
White enamel dial with steel beetle hands and an apperture for winding.
Engraved and pierced balance cock with diamond endstone. Signed ‘Conrs Dunlop London 3383’. Mid-18th Century.
A 'dumb repeater' is a watch which repeats the time by striking hammers onto the inside of the case rather than on a bell or gong. This has the effect of feeling a vibration rather than hearing a sound, much like the silent mode of a mobile phone today.
