this is an unusual electrical torsion clock made by aug.schatz & sohne .it has a electromagnet that winds a little spring every minut (more or less ,it depends by the adjustement).
On this clock it is possible to regulate the time keeping through the pendulum like the other anniversary clocks , even more moving the arrow in the back plate .
Because I don’t have the right size battery I have made a rude adapter for to use the AA battery type .the clock runs and keeps perfect time with an horolovar suspension spring (0.056 mm,as you can get from the clip).
