    Chopin reacted to Tmuir in Balance Staff Diagram for Measurements   
    I've got a 1920s Jaeger car clock with platform escapement that I need to make a new balance staff for and tonight I will measure the broken balance staff to get all the critical measurements.
    Previously I have just made a rough hand drawn sketch of a balance staff but decided it would be nicer if I had a good diagram I could use to write the measurements on and then keep it filed away should I ever have to make another ABEC balance staff.
    I was thinking of making one up in CAD from scratch but in flicking through Henry Fried's book 'The Watch Makers Manual' I found a perfect diagram.
    Took a photo of it, did some clean up  of it in GIMP and then turned it into a PDF file for easy printing. I have set the PDF to be A4 size.
    I have attached the PDF and a JPG of the image too as I thought this may be of use to other people.
    If you haven't already got a copy of Henry's book I do recommend it, as in my opinion it gives the best walk though on making a balance staff using only the equipment an average watchmaker would have in their workshop.

    I have actually improved the process by using a 600 grit sanding barrel. No lines. Then finish off with this stuff....works great on glass.

    Chopin reacted to AndyHull in Reverse Watch Crystal lookup tool for W-C Crystals?   
    I suspect you are more likely to make your money back by selling the crystals individually, but you will still need to figure out what they fit, and for that Ofreil, or even just a good old fashioned pair of calipers would be best. Measure the diameter (or shape), thickness, profile etc.
    I suspect that there may not be much interest, unless they fit particularly popular models. Personally,  I would hang on to them, and use them as the first potential source when you are looking for a new crystal for any future watch purchases.
    I have a fairly large collection (several hundreds of various crystals, all bought in similar job lots of maybe 50 or so at a time), to the one you describe, and all picked up for not much more than the cost of a couple of good crystals of known profile.
    It is surprising how often the stash yields the correct type.

    Broken balance pivot is what I was thinking as well. I can't see entirely but isn't that a breguet overcoil hairspring ?

    Unscrew the hairspring stud screw while the balance is still installed (will make things easier) and remove the balance afterwards. Don't unscrew it too much so that it falls out of the slot.
    Then you just remove the hairspring and balance like any watch, yes.

    You're not going to have much luck with this. Besides, those crystals might very well fit other watches/models as well.
    Most people don't put up watches for sale with all the numbers that they find on them in the title so therefore it's not going to be easy.
    You could look up individual watch models and then try to find them online. (still not easy) Maybe if you can find images of them in old catalogues or printed ads.

    Chopin got a reaction from Nucejoe in watch strap fixings   
    Have you tried this type of strap ? I don't know what they are called but they come in various shapes and sizes. I would imagine that the metallic rod comes out and can be replaced with such a strap and its springbar ? There are also bracelets like this as well. Not as common as the traditional ones but they exist. CousinsUK has such models, or at least had at some point.

    Chopin reacted to saswatch88 in UPDATE on porcelain dial soldering   
    Ok i finally did it, not the best job but def will pass my standards. The 60 is slightly off, the weld was a bit shabby but ok. I ended up using a tool for wood burning, its does not heat up as much as a solder iron. There is a tiny chip by the 50 that occurred when removing old sub dial, kinda pisses me off the most because without that would have been dam near perfect.

    Someone knowledgeable told me that it doesn't fit actually and from photos it actually seems to be right (or wrong in the case of julesborel website).
    The wheel probably fits but it is the "normal" short pivot version while I require the long pivot one which extends upwards where another wheel goes into.

    Risk of mishap is greatly reduced if the regulator and stud arms can be moved smoothly, I often remove/ clean and make sure both function correctly before disassembly.

    Chopin got a reaction from jdrichard in Any Hints on Repairing this Watch   
    As I said, you have to remove the rotor along with the bridge underneath it (the one that holds a few other tiny gears as well).
    The screw that holds the rotor itself is on the other side btw. You can also turn halfway that screw that is cut to remove the 2 small gears.
    Also do that once you remove the ensemble. It'll be easier.

    You have to remove the entire automatic ensemble (the weight + the plate/bridge underneath it). Usually 2-3 screws.
    Then you turn around the ensemble and I imagine you'll figure out how it all comes apart.
