A late 18th-century English consular watch in a diamond- and pearl-set gold and enamel case, accompanied by a matching chatelaine. The full-plate fire-gilt fusee movement with round pillars features a geometrically pierced and engraved cock with diamond endstone, silver regulator disc, plain three-arm steel balance, and blue steel spiral hairspring, later converted to an English table roller lever escapement. Wound through a white enamel dial with radially set Arabic numerals and decorative stone-set hands.

The gold consular case is set with diamonds and pearls; translucent dark blue enamel bezels bordered by a white enamel band are accented with split pearls. The back displays translucent blue enamel over a line engine-turned ground with applied white-metal diamond decoration. The gold pendant and bow match the fine chatelaine, which features enamel and pearl-set cartouches, three pearl chains, diamond-set bells with pearl tassels, and a coordinating gold and enamel key. Presented in a later black morocco case lined with gray velvet.
