Chequers Antiques has dated this piece to the 19th Century.

Condition: Excellent, the case is in wonderful condition and the gilt bronze mounts clean. The movement has been fully serviced and overhauled and is in full working condition. The dial has become somewhat crazed over time however it has been our decision not to repaint it. The numerals have been refreshed. The securing screw for the pendulum is a replacement. The gong has a pleasing deep sonorous tone.
