This cartel clock features tortoiseshell and brass marquetry.
The brass is enhanced with engraved details.
Engraving is also found in several places on the tortoiseshell; this engraving is white in color, to contrast with the dark brown hue of the tortoiseshell.
The adhesive beneath the brass marquetry has degraded and several pieces have detached from the substrate; some have been lost, while others were recovered and preserved by the clock’s owner.
