My firm makes what you are looking for - but in much bigger sizes - aka 24" and larger for tower clocks controller by RS-485 - but I would recommend you try and find a Takane R9 Correctable movement.

Hi

Ok, that is what I was looking for. Now if I can just find a Takane R9 in stock somewhere :)
Part number 539JX237A seems like the thing to search for. Google isn’t much help there.

=====

I looked at doing this with various “glow in the dark” approaches. The main use for the clock
will be here in the family room. I already have proven that glow in the dark objects are not
compatible with watching movies on the TV. ( Actually it was ok with me, but the rest of the
family voted them off the island …..).

Hi Thomas:

I was able to find a data sheet for the Takane R9, but not a source to buy it.
https://mb.nawcc.org/threads/hackable-quartz-movements.144625/#lg=post-1130936&slide=0

With 2 stepping motors (second Motor, Minute/hour motor)
with hands position sensor (second hand: photo sensor, minute/hour hand: mechanical connection)
Do you have a link to the manufacturer's web page?

Have Fun,

Top of the head idea:

get a cheap "Atomic Time" clock with the display format you want.
GPS receiver with Raspberry Pi/Pico/Arduino or similar to get the time and
GPS offset (use GPSD?).
extract the GPS time offset to create the time /you/ want.
code a simple emulation of WWVB/MSF/DCF-77 or whatever and make the Pi
generate a simple 60 kHz signal with the right modulation and feed it to (near)
the cheap "Atomic Time" clock.

RPi TX software can make the RPi into a transmitter:

Hi

Since I also have an empire of WWVB based clocks running around the house, generating
a “synthetic” WWVB seems risky. There will be several “Crazy Clocks” so distribution of the
60 KHz would be a bit exciting.

Faking things with a DCF-77 clock might be more practical since I have no current plans
for trying to get “real” time that way.

Once you get an RPi into the mix, an “offset” NTP server and NTP based clocks become
a viable ( and easy to get ) option.

I had pictured coming at this problem from the other end. If you have a
clock movement with press fit hands you can set it to any offset you want
from what the movement thinks the time is.

You'd have to adjust the clock each time there was a leap second, but I
hear that people are working on making this not a problem.

Hi

The gotcha there is that you don’t really know if the hands “nicely” come off and on
until you have potentially nuked your clock.

The second hand needs to be on there pretty well. It gets more drive than any other
hand. If it’s not reasonably secure, things will drift as the clock operates.

Indeed I could start tearing various clocks apart to learn a bit more about just how
those second hands are attached ….. At this point I’m just guessing.
