Speedmaster Pre-pro

What should my expectation be for accuracy with my Speedmaster Pre-pro (1964)? I took it to be serviced (Felmar in Los Angeles; it took three visits to get the chronograph working properly again even though it went in working fine, but that's another story) and it has not improved its accuracy. Before and after the service it lost/loses about 30-40 seconds a day. Is it too much to expect better from such an old watch? What does a new Speedmaster Professional gain or lose a day?
