The inverted bell top of the case originated with the last of the square dial bracket clocks, around 1710-1715, and was used throughout the first three quarters of the 18th century. When it is combined as on this clock with the stylistic features of squared vertical corners on the case, rather than canted corners, the clock can be fairly safely dated as being made prior to 1745. This particular case is constructed on an oak carcase, veneered partly in ebony and partly in ebonized fruitwood or boxwood. The finish overall is old, possibly original, and in superb condition.
Feet are proper replacements, and the brass mounts are all original.
The clock was possibly intended for export, as were other examples of Clarke's work. The two half-circles in the lunar opening in the dial's arch are engraved with a globe on a stand on the left one, and a scene with a castle with minarets on the right, again a connection to the mideast. The mock pendulum seen in its curved opening in the center of the dial coincides with movements originally made with verge escapements. The blued steel hands appear to be original and without repairs. Clarke's six pillar twin fusee movement is of eight day duration and uses its original unaltered verge escapement, with the durable and resilient knife-edge pivot that allowed the clock to be moved so easily, even while running.
