Automatic Clock Co, Chicago, Illinois, USA. serial no. 318, made in 1913.
The first photo shows the light on which was installed in the ceiling inside the
cabinet. Notice the second shot has the seconds dial present below the upper main dial.
Originally both dials were made of metal. I had the custom glass dial made to allow one to
fully appreciate the mechanism, especially when operating. The subsidiary seconds dial
will also be reproduced in glass allowing one to see the escapement and spring remontoire.
Original dials and black hands have, of course, been retained.
The large cylinder below the movement is a programmable electrical contacting device
which was used primarily to activate a bell or buzzer. This would be used in schools to
announce class change times.
