In this tutorial, we are going to cover the process of replacing a broken balance staff in a watch. This is not a difficult process, however, it will require some time and the correct tools. Replacing a balance staff the first time can be somewhat fearful. Trust me, however, it is a simple process. You’ll need some patience, proper care of the parts you’re working with, and a steady hand. (Sometimes I forget the hand part).
In the video below, I break down the process of removing the broken staff from the balance wheel, and making sure that we remove the parts correctly, putting all those aside we will be re-using.
We also cover the process of inserting the new staff onto the balance wheel, as well as re-seating the roller table and hairspring and readying it for placement back into the watch. In the video, I’ve included some diagrammed animations that may help you understand how all the tools and parts fit together to perform this task.
For a list of tools needed, see the list below the video!
Tools Needed for this project!
Screwdrivers: Of course, if you say my review of the burgeon screwdriver set, you know why I like these… To read the review article, click here.
Hand remover tools: Used to both remove hands and for prying small parts very carefully.
Roller Table Remover: There are several different versions of these
Watchmakers Stake Set: These can be gotten from a variety of sources. They are not inexpensive, and if you don’t care if you have the newest and greatest, then you can find a good version, used online from many sources. Some of the best I’ve used are 100 years old, and they are more then enough to get the job done.
Replacement Balance Staff: Now, I can’t tell you to do what I did. Over the past twenty years, I’ve purchased thousands and thousands of watch staffs. From pocket watches to wrist watches, and from as many manufacturers as possible. I’ve purchased them new, and from estate sales. This is the best way that I’ve found to obtain my collections. Those of you who are just starting out, may want to find just what you need, when you need it. Staffs are sill produced for most antique watches, and when you can’t find one, one can be made. In a future article I’ll be providing a list of suppliers for you to try. These suppliers are good for parts and tools you may need or want.
Good Luck, and let me know if you like this video. Your comments will aim me in the direction you want or need tips and advise in.
