From what I've read dirt and dried or sticky lube is the worst offender with the Borg clocks. The dirt and lube issue is something common to all mechanical clocks but along with the vibration seems to be prevalent in the auto clocks. Pitting and burning of the contacts that close to kick the solenoid when winding occurs is the next common failure mode. A weak battery from a long sit is another culprit with the contacts because when weak the battery doesn't kick the solenoid hard enough to wind all the way so it starts needing a wind more frequently which increases the arcing. If the battery becomes too weak there is no kick and contacts sit closed since the kick cannot open them. Burning until they won't pass current then is common. Hopefully the fuse finally blows before that happens but being saved by the fuse is not always the outcome.

One all to frequent issue is spraying the clock mechanism with WD40 or some other lube. That works for a week or two but to effectively lube, clock oil needs to be applied in tiny amounts directly onto the pivot points and not get on the hairspring which works the balance wheel. The overall spraying just gets everything sticky which in a short time attracts more dirt.
