And somewhere out on the net, instead of "novelty" or "alternate
timebase" clocks, for a "normal" clock someone was putting a DS1302 or a
D1307 into the mini quartz movement.
I'd love to see a DS3231 dropped in for that task.
DS1307 ~5 minutes per month
DS3231 ~few minutes per year, +/-2 ppm,
Lady Heather does have an audible "tick" clock mode. It ticks on the second
and beeps on the minute. The ticks and beeps are fairly well synchronized to
true time.
You can also set the clock name displayed on the analog clock display... Mine
is usually set to Patek-Philippe.
That is interesting. Thank you

Not sure who it would be but the reason to want to use a 1 pps step is its
easy to clock.
Though the fact that its 2 phase like you have in the pulse makes it
tougher.
The tick is the second. On a multi-step clock how do you phase the second
hand. Visually but complicated through a slew
A recent thread talked about noisy clocks (1 tick per second). Some of
you may have noticed that it's now possible to buy cheap quartz clock
movements that have a continuous-sweep second hand, and don't tick once
per second. For example, klockit.com sells two different brands (Seiko

Sounds like a Butler oscillator; very popular with Navy avionics back
