I have a 1927 Ball-Hamilton 999 watch that needs a new balance staff. I've been searching and Google'ng but I can't find what staff it uses. Can someone point me in the right direction, THanks.

I believe it would be a #434 but I may be wrong. IHC-185 member Mr. Rob Carter at Ysub9@aol.com can tell you for sure. He can also install it for you QUICKLY at a VERY reasonable cost.

Here's a photo.

You were correct Robert. Thanks for the help.
