Junghans ATO master clock

Junghans ATO battery electric type. NOT transistorised

Very collectable.I think it dates from the period 1955, the earliest transistor switched clock having been made in 1957.
Junghan ATO battery clocks are not not often found nowadays, but a master clock based on the Junghans ATO movement is most uncommon in my limited experience.

I am amazed that such a delicate movement (and the contacts are particularly delicate) could be adopted for master clock use, but the terminals pictured make it appear certain that this table model clock was intended to serve both to drive slave clocks and to act as a Program contol unit for bells etc..
