How Do You Replace A Balance Staff In A Watch? - Vintage Watch Repair
HTML-код
- Опубликовано: 23 июл 2024
- A very common issue with vintage watches, especially those without shock protection is a broken balance staff, or an excessively worn one. In this specific case we look at removing a balance staff with a bent pivot. We then fit the new balance staff, and poise the balance ready for installation in the watch. I hope it helps to provide a set by step guide for your instruction.

I've watched endless hours of watch repair on RUclips, this is the most comprehensive explanation of replacing a balance staff that I've seen. Including roller removal.
Thank you, I really appreciate your feedback.
Thanks for this video! This is the best video I've seen about changing a balance staff. I've been gathering the tools to try it myself with the help of this video!
Glad to hear I could be of help! I hope it goes well.
Nicely done! Never thought to use the Horia tool for balance staff removal. Keep up the good work and thanks for sharing 'secrets'!
Thanks Ashton, another great vid. Thanks for showing how to deal with a loose roller table. Cheers.
I use the same roller removal tool, it works well just by sliding the wheel with the roller still attached the balance staff. No need to squeeze the tool as the ledge that fits between the wheel and roller is tapered so it essentially acts like a wedge to separate the two parts.
Thank you very much, got lots information of staking tips. Great video.
Excellent video. Very informative. Thanks for posting this! Subscribed.
Thank you for sharing your experience on this excellent video.
Your most welcome, happy to share the knowledge around!
Very informative. Thanks!
You’re welcome! Glad you enjoyed it.
Thanks for this video!
I feel like I know this procedure like the back of your hand.
Original.
A great video - Thanks
Thank you, what a great informativ video!!! You got a sub 😊👍 now i start a video marathon and watch all your videos. Best regards Danni 🇩🇰
Excellent thank you.
Very good video 👍🏻
This was great, many thanks for the tips you shared, priceless. What Horia sortment of presses would you recommend? There is a set of 12 presses (Horia assortment no 3) and 6 anvils. The presses ranges from 70 to 180 (guess it's 0,7 to 1,80 mm). Thank you.
Great video with nice voiceover. Subbed
Thanks Ashton, shame your hand was often in the way, but great commentary as ever!

How do you know which side of the balance wheel to rivet the staff on?
Thanks for the video and for sharing. Now I thought that the balance screws could be turned IN or OUT in order to alter the gravitational center, was that wrong?
You aren't wrong, but also not completely correct. There are screws that can be moved in and out, but only certain screws. Most of the crews on the balance are fixed and are just there for weight. You always need to poise a balance but removing or adding weight, after a staff is changed.
Beautiful to see. Quick question Ashton... After watching this I'm looking to purchase a Horia Jewelling tool, I note there is a 3mm and 4mm spindle version does it make a difference which I buy?
Thank you and keep up the great content.
Nice
I know this job like the back of your hand.
What pusher did you use for this on the horia? I only have the pumps but they don't have holes in them.
What does your hora have as the bottom stakes? You use those in the top. The size of stake is dependant on the size of the balance staff.
@@PrecisionHorology ah you used a bottom anvil as a pusher in the top do I understand correctly?
Thanks in advance
Good informative video, giving me confidence to re-rivet my own. Pity about the hand which obstructed the camera at the wrong moment in that you were turning the stake between hits. Henry B Fried or Archie B Perkins said to use a brass headed hammer for stake work, so I always do - can you comment on that?
Honestly, not really. I'm not sure why a brass Hamer would be better to be honest. Could it be a weight thing?
@@PrecisionHorology From what I have read, a brass hammer has less chance of damaging the end of the punch where you strike it. The end of the punch will get mushroomed over time and it will be hard to insert the punch in the inverted position (used as a stump).
I've never seen any damage to my punches, they seem to be just fine. But thanks for sharing that. @@johnhannon
So you dont cut the rivet on the lathe first, before you press the staff out with the Horia?
No, you either cut out in a lathe or press out.
You should cut the rivet or use a a special tool called molfres to prevent the balance wheel hole decentering
Is this the most common problem with mechanical watches that won't run ? I'm looking on Ebay and wonder what is the reason many vintage wind-up watches won't run.
It's one of the problems, and when it comes to watches before shock protection it can very likely be the culprit. Many watches won't run though just due to the fact that they haven't been serviced and all the old oil is gummed up.
@@PrecisionHorology Thanks you. Assuming a vintage mechanical watch is only gummed up, how long of a job is to have it cleaned by a professional ? Just trying to figure out the costs. Assuming a standard wind-up model.
@Peppermint1 entirely depends on a number of factors. The watch in question, etc. too many factors to say.
Well, unfortunately, I missed a lot of the critical parts of this procedure, but I am now very familiar with the back side of your left hand.
I tried to keep my hand to a minimum, but I am only an amateur videographer. If you can’t fill in the blanks of when I’m turning the work piece or hitting a stake with a hammer, I’d suggest a new hobby. Watchmaking may not be for you…
