Pendant Watch
The movement of this watch is signed DUTARTRE A PARIS, which refers almost certainly to a member of the Dutertre dynasty of watch and clockmakers. At the time this watch was made, several Dutertres were active in Paris: the brothers Jean Baptiste, Jean Abraham, and Nicolas Charles Dutertre; and Nicolas Charles’s two sons, Jean Baptiste and Charles Nicolas Dutertre. Watches decorated like this one, in various shades of gold, were particularly fashionable at the time. The colors were obtained by adding alloys to the precious metal; for example, copper, to achieve a pinkish tone.
