Verify Before Ordering

A conversion kit should not be selected by the old model number alone. Before ordering, verify the complete number stamped on your movement, hand-shaft length, movement pendulum length, plate size, hammer location, dial clearance, mounting arrangement, and chime configuration. Installation may require adjustments or case modifications and should be completed by someone experienced with mechanical clock movements. Contact us with clear photographs and measurements if you are unsure.
