Hi,

I was trying to fit a new click ball and spring today on my beloved 6309-729A. I seemed that something was in the hole blocking the spring from seating all the way down. I ended up removing a sleeve from the holeThe lower end of the sleeve is peened over while the other end is open. But there is something in the sleeve that is keeping the spring from going into the sleeve.

Have any of you encountered this? The drawings I have look like the hole in the case should not have anything in it. But the spring I have is too short for it to work that way. 

Also, should the ball be just loose in the hole? It can fall out quite easily.

Any help with this would be greatly appreciated!

As far as I know the ball should not be loose. It should be quite tight.

I remember that I tried removing such a ball from a hole and spring once and I couldn't do it because it was so tight that I didn't have any grip to extract it. (it did go inside when pressed so it worked fine)

From the beginning it was a complete unit. A spring inside a sleeve and clickball on top. But when it's worn the ball falls out. Leaving the unit still inside the case.  Then it's easy just to put a new ball on top of the spring and it will work fine again.  put a dab of silicon grease to hold the ball there until you have placed the bezel back. Put a new gasket in the bezel and you have a nice working bezel again.

As it turns out, you were right on the spot Rogart63. I got a small drill bit and cleaned out the years of gunk that had dried up and hardened in the sleeve. Once I did that the spring appeared still in the sleeve. Took it out, cleaned it up, put it back together with a new ball. It works like a charm now. 

Thank you!

Mike

Thank you Rogart63! That is it. I guess the case must be a 7002 because those are the pieces. Now I just have to figure out how to get the rusted spring out of the sleeve.

Thanks!

    I use penetrating oil to remove a rusty part,  let soak for a while.  vin

      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.
