Me and a buddy have a little podcast re affordable watches, and last week we talked about quartz movements. We're total quartz newbs, and the information was largely gleaned from what we could learn on the internet, including, heavily, the very good sticky (here) called Thermocompensation: Methods and Movements.
Anywho, we got a question after posting our episode this week, and I don't know the answer. I thought some of the brains here may be able to help me. The question is basically this:
Why is 1-second the standard output for quartz movements?
For context, and to perhaps avoid some surface explanation, I know that standard quarts oscillates at 32,768 hz/s. That number is important because it is a power of two, and, thus, allows, through a series of 14 electronic "flip-flops," conversion of the output signal to 1 beat (or really two - tick and tock) per second.
So why not, instead of flip-flopping 14 times (converting 2^15 to 2^1), flip flop some other amount of times to make a "sweep." theoretically, couldn't one flip flop 11 times (converting 2^15 to 2^4) resulting in an output of 8 "ticks" per second? That would practically replicate the the standard 28,800 standard of mechanical movements. I think that most mechanical lovers are generally of the consensus that more beats is better, so why not here? I assume that there MUST be a pragmatic reason for the decision - I just don't know what it is.
I know that Bulova does something like this with the precisionist movements, but I am made to understand that they do this by an exceedingly fast initial oscillation. Why does the initial oscillation have to be so fast?
