A late 18th Century French verge in an unusual silver skull with masonic symbols. Full plate gilt fusee movement. Finely pierced and engraved bridge cock with steel coqueret, plain three arm gilt balance with blue steel spiral hairspring. Blued regulator dial with gilt indicator. Winding through the signed white enamel dial, Roman and Arabic numerals, decorative pierced gold hands. Substantial large cast silver case in the form of a skull. Realistically modelled with deep eye sockets, nasal passages and carved teeth. The top half of the skull pierced and engraved, small circular cartouche at the back with masonic symbols of a square and compass. Hinged at the back, opening to reveal the dial. An interesting piece made in early 17th Century style. Probably intended as a small desk clock.
