This is a new item we custom ordered to widen our range of quartz clock movements. This is both a trigger movement with two wires that close a switch inside the movement once an hour to trigger a sound module and also a high torque movement tested successfully with our longest hands. We recommend it with any of our "I" shaft hands up to 17-1/2" long. The hand shaft has an extended minute hand mount for extra spacing between the hands to help keep them from rubbing on each other. While this movement can operate a second hand we don't recommend using one with hands over 8" long. Includes mounting hardware: flat washer, hex nut and minute hand nut.
