Every clock I receive for repair goes through a very thorough overhaul process. Everything is disassembled and all parts are prepared for cleaning.
The movement is cleaned of accumulated grease and dirt in an ultrasonic cleaning machine.
All pivots are restored to a high polish using a clockmakers lathe and pivot polishing file.
The movement is examined and all worn pivot holes are bushed.
All other relevant parts are polished and repaired. The movement is then reassembled and tested.
