French early 19th century ormolu and marble greatwheel skeleton timepiece

This early 19th-century French skeleton clock, specifically a 'greatwheel' timepiece, features an elaborate inverted Y-shaped ormolu frame decorated with burnished and matt finishes.

The framework is punctuated by lion mask mounts and leaf-cast supports, resting upon a white marble base bordered with beaded ormolu mounts and standing on ball-and-claw feet. The 2.75-inch enamel dial displays Roman numerals and open Breguet-style moon hands, with an open center showcasing a star-shaped center wheel. The mechanism is a chain fusee movement featuring a prominent 5.75-inch diameter great wheel with eight tapering crossings, complemented by wheels with five and six crossings, terminating in a delicate pin-wheel escapement.

The large spring barrel is positioned between lower supports with skeletonized caps. The clock stands approximately 35 centimeters high and is accompanied by a winding key. The assembly is currently housed on a mahogany base beneath a paneled glass case. The piece represents a significant example of French horological design from the early 1800s, emphasizing the intricate exposure of its internal gear train.
