Seth Thomas 89 Suspension Spring – Complete Unit
This Seth Thomas 89 suspension spring unit is intended for compatible Seth Thomas #89 mechanical clock movements. It measures approximately 15-1/2 inches overall with a 1-3/8 inch spring section.
The suspension unit forms the flexible connection supporting the pendulum and must match the movement geometry closely. A broken, fatigued or distorted suspension can prevent the pendulum from hanging and moving correctly.
This replacement is particularly useful for restoration of clocks fitted with the Seth Thomas #89 movement where the original unit is missing or no longer serviceable.
