Case of well figured walnut and olivewood veneered on oak, formerly-rising hood with shallow dome top above a fretted frieze and gilt swags, the dial aperture flanked by Salomonic columns, the convex throat moulding above the rectangular trunk door inlaid with geometric patterns with boxwood borders framing walnut and central olivewood oysters, ogee moulding to the plinth on bun feet.
10½ inch square gilt-brass dial with four latched dial feet, the finely matted centre with calendar aperture below XII, superbly sculpted blued-steel hands. The skeletonised silvered chapter-ring with Roman hours and dot half-hours, every minute numbered. Flanked by winged-cherub spandrels with a wheatear border signed Joseph Knibb Londini Fecit along the lower edge.
Massive three-train weight-driven movement, 7¼ by 8¼ inch plates, split for each train and secured by ten finned baluster pillars, six latched, going-train with anchor escapement and butterfly adjustment above the backcock. Strike train governed by a large diameter outside countwheel, the quarters by a smaller outside countwheel, linked by a pivoted lift-off lever. The larger bell struck for the hours, the smaller for the quarters.
