Not me, but a few years ago I repaired the clock in a 1980 Ferrari 308
-- I didn't really think to take many photos, nor did I bother to
check the accuracy, but over the course of 3 or 4 years it was always
"right" (the time showed accurately enough that I didn't notice it
being wrong (modulo DST!)).
This was a quartz unit, made by Veglia Borletti - the issue was that
the tip had sheared off the staff on of the wheels had sheared off
(see photos) - I initially tried repairing it with some tiny pins and
CA glue, but ended up getting another clock from an Fiat and
scavenging the wheel from that...

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
