The plain brass case is enhanced with large ornamental patterns on the front and sides. The dial of this lantern hanging clock carries a brass hour circle, probably not original, with Roman hour numerals and markings for the quarter-hours and the half-hours. The circle's oversized design is known as a "ram's head." The movement has two trains supported by separate pairs of uprights; both trains are driven by weights with ropes. Winding is by counterweight. The verge escapement carries the short, thin pendulum rod oscillating between the two compartments inside the movement. The chime is controlled by a 12-stroke regulator. Originally, the "wings" probably protruded from the sides. These were brass triangles that protected the wide oscillations of the pendulum in models of this kind. Lantern clocks acquired typical features in England from c. 1620 onward. Their convenience and reliability made them popular across Europe. The invention of the pendulum was incorporate late in lantern clocks and did not alter their other characteristics, except for the model with side-wings, as this specimen probably was.
