First it needs cleaned, adjusted and repaired, and then it needs lubricated with the correct lubricant (hint: it ain't 0 weight synthetic motor oil).
If the clock is worth repairing and making it right, find yourself a good local clockmaker and have them get it in running order. They'll disassemble it, clean it with the proper clock cleaning solution in a cleaning machine, replace worn parts, polish pivots and replace worn bushings.
We've had both of our 1850's vintage German wall clocks restored by a horologist; they're family heirlooms and we would not have entrusted them to anyone who would consider lubricating them with "0 weight synthetic oil" and calling it good. Both clocks run like new and keep perfect time.
