I am not sure Ford used quartz in any clocks.
Low cost quartz clock applications occurred in the 1980s
By the early 80s, Ford was into electronics such that the clock was incorporated into the radio.
Pretty sure Ford went from mechanical to electronic in one step.
And for any given model year the clock us usually unique to that model year. The clock may have been shared with full sized Ford and full sized Mercury. But the following year things like that would have changed to keep the new car buyer from getting the same car as offered last year.
The mechanical clocks are supposed to adjust when reset assuming they are operating correctly. It may take several adjustments.
