John Graff was an exceptionally skilled Swiss portrait enamellist, who produced work for many noble families across Europe. He also specialised in portrait miniatures of Indian and Chinese dignitaries.

The movement of this piece is complicated. The clock watch feature will automatically sound the times, thus at the hours, the hours will be struck, whilst on the quarter hours, the hours and quarters will be struck.  The repeating functions are powered by their own barrel and spring and as such, the crown will wind the repeating barrel when wound one way, and the mainspring when wound the other.
