Case: Case of figured walnut veneers onto an oak carcass, hood with dome and riased top and cross-banded walnut plain frieze below, brass-capped Doric columns, with concave throat mouldings above the rectangular trunk door, concealing the pendulum beat scale to the backboard, the plinth with feather banded inlaid panel above a double footed skirt.
Dial: 11 inch square silvered regulator dial with large subsidiary seconds set above the recessed hour sector signed Geo Graham London with finely sculpted blued-steel minute hand and counter-balanced seconds hand, pin-hole adjustment to the calendar aperture and bolt-and-shutter lever by 15, blued-steel securing screws to the dial feet with steel location pins.

The movement secured by means of two bolts through the seatboard into the base pillars and by two robust T-form securing brackets to the backboard. The dial feet screwed to the front plate.
