I bought this clock off of eBay in April of 2014 for $24. I found it a bit unusual because it uses 2 C cell batteries to power it and has a small synchronous motor in it instead of a stepper motor to run it. It is manually started by pushing in the set knob after setting the time. It runs very smooth and of course has an extremely smooth moving second hand. It does make a bit of noise but when the back door is on it is hardly noticeable unless you listen right next to it. I believe that it is from 1974, and is very accurate. I figured that I would start a new post about it because it seemed to spike some interest on the quartz clock post. I can add more pictures if needed.
