Trying to put the hairspring collect back on and managed to push the balance staff out. This is why I'm practising on a Ingersoll dollar watch I bought for fiver!

Still - can I repair this? The balance staff is now loose.

It looks likes someone got a bit too aggressive with the graver when they were cutting off the rivet. If it came out by just pressing the hairspring back onto the shoulder, it wasn't held in very well to begin with. That hole in the balance arm looks pretty hogged out. I doubt if a replacement staff would fill that hole. One would have to turn one themselves. Good luck.

hmmm - superglue time :D

So the balance staff has been replaced at some time in the past?

Would love to be able to know the history of this watch. Purchased in around 1892 for a dollar - bet the first owner was chuffed. Then 130+ years later on my desk and on it's last legs.

If you have a staking set you could try closing the hole on the balance wheel. Start with a hollow domed stake and finish with a flat, making a friction fit possible.

It’s called swaging. Careful in doing it and support it well as you could distort the balance arm out of plane and add another problem.

I have a staking set - just not much knowledge on using it. I'll try and see what happens.
Remember when fitting the wheel to the staff to set the impulse jewel 90° to the balance arm. Either way the watch will require to be in "Beat"
Mark has an excellent video on how to do this .

      I'm going to be setting up a decent little workshop here at home.

      By Michael1962 · Posted

      Well I put the spa on Gumtree (selling service) to try and sell it as it only needs a recirc pump to get it going. However, it weighs circa 250kg, so there's 4 fairly strong guys, and I would have to remove the sliding door in the room completely to be able to get it out, as well as clearing out a multitude of potted plants and the Alfresco outdoor setting to be able to get it out. Then move nearly everything in the back of the garage to be able to push it through to the front of the house. I would also need to hire furniture skates to be able to shift it around as carrying it is out of the question. Then someone would need a trailer to get it to their place as you won't get it on the back of a ute. So, the only answer is, out with the reciprocating saw and cut it all up into manageable pieces. Crying shame as it is in really good nick. I was only asking $1,500 and only got two bites, but it would only take something to go wrong with removing the sliding door etc that everything I make on the sale could go out the door on repairs etc. It would have been nice to be able to turn it into tools etc, but que sera sera. I don't know about the rest of the world, but there just seems to be very little interest from people wanting to buy things secondhand.

      I would like to see the movement. The watch is the movement. Anyone can print a name on a dial and sell it as "the maker".

      What are these Seitz B-Jewels?

      By VWatchie · Posted

      Thanks for your answers! There seems to be a contradiction between these two answers, so perhaps I need to clarify. The flat and convex jewels look identical on the side facing away from the pivot shoulder. That is, there is an oil reservoir. I don't know if that changes anything but I thought it was safest to clarify since I didn't include a picture of the jewels from the opposite side.

      unfortunately paying attention to details bumps up the cost. Which is why they shortchange on manufacturing steps if they can.

      Introduction

      Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement.  When it comes to tools buy the best you can afford a good set of watch makers screwdrivers if you look after them will last you a life time. I recommend Dumont tweezers Number 3 and number 5 for fine work, you can build up from there. You will need different strength eye glasses. Some now like to work using a microscope. Pliers the box jointed ones are best they don't go out of line.
