The early clock is mechanical but wound up by a solenoid. Normally it just needs cleaned by a jeweller if such a trade still exists. I got 2 cleaned years ago and still going well.
I've also found several where the solenoid doesn't work but the fault was always the same, a broken wire which was repairable. It's difficult to explain, you need to release the 'wind up spring' then connect up to 12v. If the solenoid makes a loud click then it's ok, just try to get the mechanism cleaned if it looks ok.
I've often thought of providing a repair service but the clock expert I used has retired and never got around to finding someone else. I must make a few enquiries again.
The later clock is electric, straight swop I think apart from the hole which you need to drill in the front bezel to adjust the time.
Rev counter, don't know. If you're in the DSG they had a few second hand 7 dial dashes.
