This is a brand new movement that will run smaller pendulums or up to a grandfather clock size lyre pendulum! This will save you money by allowing you to use an inexpensive battery movement to run the time and this movement to run the pendulum instead of purchasing a large mechanical movement (over $100). This will also work on wall clocks.
Overall size: 8-3/8" high x 3" wide x 2-1/8" deep.
Mounts inside your clock case with pre-drilled mounting holes (screws not provided).
Requires a depth of 2-1/4".
The detached battery compartment is 1-1/2" wide x 2-7/8" high x 1" deep. The 14" wires easily clip onto the movement
Runs smaller sizes or up to a 42" long pendulum with a 10-1/2" bob.
Requires one 'D' size battery, not included.
