Thanks, that detail helps. I took it apart and could not find any break in the conductivity and the works are pretty clean. I sprayed a little contact cleaner anyway.
It will beat a few times weakly when first installing the battery (after leaving idle for a while). This is no different than before taking apart. Does this point to anything?

Hi
There should be a trace going from the coil to the IC ( black blob ).
With your voltmeter, set on low volts DC, you should see the
needle jump every second. The other lead should be on the battery
( the end with the least static needle movement ).
If the jumping reduces in amplitude, it would indicate that there
is a problem with the IC.
These are not normally replaceable. One can remove on from
another quartz clock though. One would cut the PC board, carefully
around the blob. Leaving enough traces to solder wires to.
One would have to trace which wires went where at they might
radiate differently on a different movement.
One has to be careful not to twist the board will cutting or it
might damage the chip under the blob.
It is also a good idea to keep the crystal ( small aluminum tube )
and adjustment with the blob.
Remove the blob in a similar way from the original.
Such surgery is possible but I've never attempted it my self.

Hi
One other thought.
Is the hour wheel plastic?
If it is, there is a chance that the hour hand has
squeezed it enough to jam the movement.
Remove the hands, dial and hour wheel. Then
see if it still stalls.
