I have a watch that is timing fairly well on the timegrapher however the minute hand slows to a near stop when it reaches the 31 minute mark.  I know the amplitude could be higher and the beat error could be a little less however I’m not sure what is happening with the minute hand.  Any suggestions?  Thanks

  If the movement is cased ( as in the picture) minute hand might be rubbing on the glass, otherwise clean and inspect all parts mentioned above.

So this happens once every minute, simply remove the minute hand ( the hand that goes round once every minute) this is a simple  process of elimination.

In case the issue persists, the fault is within the minute train and/ or date jumper.

it would be nice to have background story? In other words you found this watch laying on the street and tossed it on your timing machine or you recently service this watch or what what's the background story of the watch?

Then one position timekeeping on the timing machine is not quite worthless but almost. Why don't you give us another picture crown down position just because. also the graphical display doesn't look quite as nice as it should be looking when was the last time the watch was serviced?

      Just a note for those who come searching for information on this topic in the future.  I did eventually find the Mark's video on how to replace these springs, as someone observed, he does in fact make the replacement look easy.  (It actually is relatively easy once you have the knack of it.) If you're enrolled in one of Mark's online courses, the demonstration of how to replace this spring is in the Bonus Videos section of his course site, and is called "C2B1 – Sea-Gull Style Shock Springs".

      If the metal was twice as thick, it wouldn't snap so easily.  The thickness is governed by the space available so you can't use thicker metal.  If you glued two pieces together, the likelihood of snapping would be reduced.  That's my theory anyway, could be wrong.

      there are various approaches to learning watch repair. A lot of people want to jump right in and every single watches something to be repaired restored. But other times like this it's disposable it's here for you to learn and when you're through learning you throw it away. yes you definitely should try this you have a learning movement you need to learn and the best way to learn is by doing something.

      Sorry, the friction will be so great that the wheel will barely turn, if the movement will start at all, the amplitude will be verry lo.

      If I can’t re-pivot the wheel, the logical thing to do is to descend the pivot hole.  Plan is to either stick a suitably sized hole jewel (from a barrel bridge or something) or fashion a blob of epoxy on the underside of the escape wheel cock so the wheel sits on its one pivot on the base plate and the staff with the broken off pivot (which I’ll polish as best as I can) becomes the upper pivot. As long as it doesn’t foul the 4th wheel it should work? I know it’s a bodge job, and if this were a rare movement, or belonged to someone else I would not do this. I’m just interested to see if I can get the thing to run.
