Got an Urgos grandfather clock with one of those self-adjusting escapements which appears to have gone out of whack. The movement has been cleaned, lubed etc, but it runs as before -- gaining maybe 20 minutes a day. I've checked out the weights, wear, suspension and all the usual suspects but don't see anything. The pendulum swing seems very narrow but that might be typical for this kind of movement -- I've not seen one before.
If the escapement unit is shot, can it be repaired? Is there anywhere that will sell me another one?
