how did you remove the balance staff from the balance wheel? Did you notice that the balance staff is slightly different than something you've seen before? In other words did you notice that the balance staff some of it is blue in color?

 

[Murks]

Yes your right some of it is blue in colour how did you know what does that mean?

I found a nice picture to show the problem. When you replacing balance staffs you want to be very careful to pay attention to blue steel parts which are used to indicate that it's not a regular staff and that it's a friction staff. Several American watch companies have used friction staff as it makes it really nice to change them providing you don't accidentally drive out the blued steel part then it becomes a pain to get this back together again. So if you're lucky can put the blued steel part back into the balance and you still need to get the staff out. Might be easier to do it now that the whole thing is out of the balance wheel but the blued steel parts still has to go back in.

Then because you probably don't have the nice punches that the show is none of us do if you're really careful you can find something in the staking set to get the staff in and out you just have to be super super careful.

Thanks alot I understand say if that blue friction got broken are there replacement for it or does it mean you need to buy a new balance  wheel reason I'm asking a got two of those movement one a believe have lost the friction blue bit ?

That's why, when I started messing with watches, I chose Waltham pocket watches - the friction fit staffs. Fitting a regular staff sounded too scary. These are nice and easy for the beginner.

possibly at one time the hubs were available separately. I have seen hubs in a bottle of replacement staffs but don't remember which watch company or which staff that was. So know that at least one company had an upgrade upgrade from regular balance staffs to friction staff's. So perhaps at one time they were available.

If you could find a really broken watch you perhaps could steal the hub from  that for yours. I know they can go back in if they accidentally come out because I've done that at least one time.
