I bought this clock as part of a bundle at an auction and it was properly stored by locking the pendulum and removing the battery. However, the battery holder terminals are corroded and the movement will not run when unlocked and jumper cables were attached to the cleaned wires.

I did continuity testing to determine that the thinly insulated wires are not broken nor shorted in their way to the motor unit.

Because this is my first clock of this type (which I have always wanted to add to my collection) I cannot speak from experience what might be wrong. It is also branded as KIENINGER & OBERGFELL.

Also, based on photos of other clocks, I think that a black plastic coveting on the base has been removed.

The glass dome is perfect. The movement looks very clean and runs nicely with manual movement of the pendulum.
