Pierced and engraved balance bridge with polished steel cocquerette. Three arm brass balance with blued-steel, flat spiral balance spring. Silver regulating disc engraved with 'R, 1 - 7, A' with a blued-steel hand. Potence plate engraved with 'Gregson', 'Horr du Roy', 'A PARIS', and 'No1424'. Pillar plate stamped incuse 'SN18' and further illegible scratched marks. Hour wheel scratched with '1791'. Composite dial consisting of a previously enamelled copper plate (enamel now removed), overlaid with a later gold coloured dial with raised polished gold Roman hour numerals and matted, floral engraved centre. Winding through the dial at II. Gold spade and poker hands. Open face gilt metal case with plain pendant and bow. Stamped inside case back makers cameo mark with ' T R ' (Thomas Rogers?). Engraved on case back with the words 'Lady Emma Hamilton 1801'. Convex glass over dial. The watch comes complete with a watch key and locket, which are attached via a chased gilt metal split ring and red cord to the watch. The watch key is made from rolled gold and steel, and is set with an oval bloodstone and an oval faceted foil-backed pale yellow transparent stone. The gilt metal oval locket contains plaited hair behind an oval glass insert. The locket is decorated with an engraved scroll motif and blue enamel infill. The watch movement has been altered to fit a later case (probably made circa 1830), the gold dial made circa 1840(?). The engraving and date on the case are evidently spurious.
