400 Day Anniversary Clock Parts
The suspension spring on your clock needs to be replaced if its kinked or distorted. Read More »
The suspension spring is the part on the back of the clock that supports the pendulum balls in the air. This is almost always the fist issue to deal with to get the clock running. This happens when someone is not familiar with the clock and they move it from here to there with the pendulum getting knocked around and the spring gets twisted and kinked.

Used to release the power in a wound up mainspring. Key goes into the chuck and the chuck goes into the handle so you can let down the power of the spring. It does the same job as the let down with all the chucks. If someone were to take a spring driven clock apart without letting down the mainsprings, bad things may happen. The movement would get ruined and you can get your hands hurt.
