'83 240D - clock intermittent

[ironandsteel]

Ok- this is a trivial issue, but it bugs me. The clock sometimes works, but mostly not. I was driving yesterday, and set the clock. It kept time for 20 minutes then stopped.

Is there something I should lube in the clock? Do these always die, or were they pretty good in general. I just want to know if it is worth my time to mess with it- maybe they are just a bad design?

The car did sit in a barn for 15 years un driven, so I guess I can cut it some slack.
