  1.  @zeroone8800  The motor may spin continuously but on these quartz movements it is driven by a quare wave, AFAIK 8Hz. Essentially the motor itself is a mechanical digital to analog converter with a low pass filter.

  2. That sounds like a neon lamp. If so, I'm surprised you could read by it. I had a clock with one and I couldn't even read the digits with it.

  4. I actually have seen an old battery-powered flip clock at a yard sale before, but as it appeared broken I did not buy it. I regret that mistake. Regarding flip clocks not flipping the minutes card very consistently, couldn't they just use a mechanism similar to the extra catch on the hours cards? The extra minutes catch would then be activated by the seconds "hand". And one last thing, a good aspect of my rolling-digits clock (similar to your stock footage but with a continuously spinning seconds wheel) is that the alarm time is exactly as you set it because it is tied to the intermittent movement of the tens of minutes wheel. I consider myself an amateur electric horologist myself, btw.
