The frame cast of 6mm thick plates with chamfered edges, formed as a circle on a pair of scroll supports with central vertical tapering section to carry the wheel train, the skeletonised Arabic chapter ring with milled edges and dotted minute marks set in front of an open circular front plate with chamfered inner edge to a solid circular backplate united by two turned pillars, the going barrel movement configured so as to ascend the central section in a straight line, with five spoke crossings of extreme delicacy terminating in a deadbeat escapement, the pendulum with a steel rod terminating in an 'axe-head'-shaped bob, with rise and fall regulation via a screw above; the backplate carries a series of three pulleys united by fusee chain combined to drive the hands, the whole mounted on a signed and numbered chamfered oval base with additional base below on an associated mahogany plinth under a glass dome. 36cms (14ins.) high
