Large Siemens Slave dial for master clock

circular metal, marked "Siemens"
Size: 17" diameter dial with very bold markings.

Armature rotates so no loud clonk as the hands advance. This operates on the continental system which uses pulses of alternate polarity. A poor/jittery contact will still only advance the clock one pulse. The hands do not move until a pulse of the opposite polarity is received.

Normally used in parallel with a Siemens Master clock. Circuit adjustable for use with 12,24,48 or 60 volts.
A very neat slimline slave, only 1.7" deep.
