The clock's mechanism is housed in a hermetically sealed capsule containing a gas mixture, which expands and contracts with temperature changes, winding the mainspring. Condition: Good condition. Some wear to the gold plating on the base. Runs, unknown service history. No guarantee of timekeeping accuracy. Dimensions: 9.25 x 8.25 in Weight: 11.3125 lb
