I am looking for a physical clock (not software) that will indicate local

reliably read 12:00 throughout the year.
Once you buy into a microprocessor, it's pretty easy to make all sorts
of clocks.. When I built the Mars clock, I also thought about how cool
it would be to building a clock that reads 6 at sunset and sunrise, 12
at noon/midnight, or, for that matter, using conventional analog clocks
as the display device for relative positions of astronomical bodies
(e.g. moon, planets)
Sort of a "locally centered" orrery.
I've also contemplated building a satellite pass clock (as opposed to
displaying it on the usual screen display). Over the years I've had
opportunity to care about when a particular satellite was above the
horizon and where it was in the sky, and some sort of "at a glance"
display would have been useful.
For example, last year I was doing some experiments with measuring radio
propagation from the ground to a radio on ISS, so there was a whole "get
ready for the measurement, ok, it should be over the horizon now, etc."
And you're doing this outdoors in bright sunlight, and it would have
been handy to have a big analog dial to look at (like the start clock in
some races)
