[time-nuts] Any time-nuttery for spring-wound car clocks?

[Gregory Beat]

Tim -
Classic (Antique) Automotive collectors desire working dashboard clocks.
There are two (2) approaches (authenticity vs accuracy): 
Mechanical Restoration OR Quartz Movement Replacement.
The restorers will tell you the mechanicals were not really accurate (long time-frame).

I am aware of two well-known restorers in that business, there are likely others.

Has anyone done any time-nuttery with the mechanical clocks available in
cars up through the 1970's?

These were typically spring-wound mechanisms with a solenoid that winds the
spring when it approaches wound-down condition.

I can find some good articles on the interwebs about reconditioning and
repairing and calibrating these

What I'm more interested in, is actual measurements related to temperature,
vibration, and other environmental factors.
