      Servicing notes

      Cleaning, lubrication, mainspring and pivot work belong with a qualified watchmaker working from calibre-specific documentation. Conserve original parts: replacing a worn component with a modern substitute changes the object, and refinishing plates or dials destroys evidence.

      General guidance only. Antique movements should be serviced by a qualified watchmaker.
