The dial and movement are contemporary but the back plate has been cut down to fit into the case. The dial plate has a greenish tinge to the edge characteristic of 18th century enamelling. Above the dial glass a small hole remains for the adjustment lever to raise or lower the pendulum so that the running speed could be speeded up or slowed down. The glass plate in the back is a later replacement as the back would originally have been entirely of metal. Originally lined with red silk to let out sound."@en . .
