Richly engraved and decorated oignon watch [French for "onion," referred to in Italian by the pejorative cipollone or "big onion"]. Has a movement with chain fusee and verge escapement. The gilt brass dial has blue Roman hour numerals on white enamel cartouches. The single hand is of burnished steel. Signed "Gribelin à Paris," in all probability the watchmaker Nicolas Gribelin.
