Service a vintage watch before selling?

[Maxf]

I've decided to sell my '78 Rolex 1680 and was wondering if to get it serviced first.

It's obviously vintage and has some qwerks, like setting the watch can be a pain and the datewheel takes a few hours to line up properly. Obviously the cost of servicing is a consideration, but it is also a very original watch, with the original crown (which are pretty rare) and things like that.

Any thoughts?

If its keeping good time, i'd be inclined to leave as is.
Let the new owner decide if/where its serviced.
