The flat-top mahogany-veneered case features contrasting burl accents across the frieze and base, alongside full-length turned columns terminating in Corinthian capitals on the glazed trunk door. The movement is reported as a year-duration time-only mechanism equipped with maintaining power, a deadbeat escapement, and crutch beat adjustment. It drives a two-piece 10 1/4-inch porcelain Roman numeral dial with an auxiliary seconds register, regulated by a seconds pendulum featuring a brass bob with an enameled status indicator.
