This is a small rose gold cased verge watch, by Dufour, Ceret & Cie, made around 1770 in Ferney, France. This is the watch manufactory, founded by Voltaire in the mid 18th century.
MOVEMENT : The gilded verge fusee movement is signed but not numbered. It is running well.
DIAL : The signed white enamel dial is about 30 mm in diameter. It has repairs on the edge at 9 and around the winding aperture. Excellent original gold hands.
CASE : Diameter 36 mm. Nice little case in two colours of gold, rose and yellow. No marks but tested as high carat gold. The only damage is to the catch button which is dented.
Dufour, Certet & Cie are listed as being at Ferney in 1770.
