    I picked up a nice looking watch with calendar display and it has a MST 404 7 jewel pin lever movement.

    The movement winds sets and runs and the calendar works correctly but the movement is losing 25 minutes a day dial up.

    I have a great watch repairer but before I send this watch for servicing I wanted to know if after a good cleaning oiling and timing do these movements keep reasonably good time?

    I don't want to spend $150 to $200 just to see it still runs minutes per day out.

    What I feat the most about these movements is wear to the pivot holes in the plates, then repair is definitely not cost effective. Personally, I think you could do better investing that money is a nicer, working day/date unless it has any family provenance.
