    Looks good. As one makes progress in polishing it becomes important not only to obtain the best possible result, but to get there quickly and with the minimum effort and mess.

    How bad is it . Can you polish the crystal. With wet and dry paper and  ceriumoxid.

    Chopin reacted to jdm in Solutions for changing vintage watch glass   
    So many topics written about this, but the same questions are always asked. In short:
    Only wet paper removes scratches. Depending on various factors, there is no set grade. 400 or 600 are the rough ones to start. 
    Wet paper is not an effective way to finish work after, say an 800 or 1000 grit pass. Use diamond paste on an hard wheel instead. 
    Cerium oxide is not indispensabile. You may find that if fact it does nothing than fine diamond paste does not do but seems harder to clean.

    Have you used a rotary tool? Without it you would spend a lot of time for little progress. And the tool must be kept steady by some sort of holder.

    I use diamond paste to.  I polished this with 400 paper then 800 and last 1200 wet . And last diamond paste . As i didn't have any ceriumoxide. Result is pretty okay?

    If you download the watch glass document you will see a better picture of the profile. Look at the MDT

    Happy Holidays.
    You seem pretty happy about watchmaking in general. I'm so frustrated with a damned Tissot 2250 plastic movement not running correctly. 
    Again, Happy Holidays to all and best wishes for the next year.

    Check the balance pivots for wear and the balance jewel cap stones for dirt.
    Do you have a watch machine if so what is the amplitude?
    Of course it could just be a weak mainspring, did it look set when you removed it?

    Some crystals, like the one that is in the video and owned by the OP have absolutely no lip to grab with a lifter. So there is no other choice. Remember that our Mark is not in the business of teaching how to damage watches, but exactly the opposite.

    The hole made the most sense once I realized that the other spot was a bit far from where most releases/detents would be. Good luck with the job.

    The thing is that I loosened that screw near the stem (quite a bit) and it didn't work but I might have to retry.

    Chopin got a reaction from Johnnie in Names of movement parts   
    I know what you mean, sometimes these things are pretty hard to find. It's probably a bit difficult to do this as each movement has it's own type and it's parts and you won't really find one movement to show all types of parts. Here's a couple of images that should help.

    Chopin reacted to AndyHull in Why does this barrel say do not open   
    Here is my tuppence worth. Clean the rest of the watch, re-fit the barrel. See if it works. If so... stick. If not, then, and only then look at how to open the barrel in a non destructive manner. If that is not possible, then you would need to start hunting down those hens for their teeth.
    The only "technical" solution I can think of and this is a worst case solution, if you have absolutely no other option,  would be to very carefully drill two tiny holes in the face of the barrel with a spade drill,  to allow you to flush it out with cleaning fluid, then add a couple of drops of oil. That way you get some cleaning done without killing the thing.

    Chopin got a reaction from DocJo in I'm in shock. Ultrabloc? Hercules? Unisafe? DeSade?   
    Found one of these on a Baumgartner movement (158?) installed in a Sicura.
    It is tricky to work with it but not if you improvise a bit.
    In situations where parts might jump around and get lost I place the movement in a transparent plastic ziplock bag and then work on the movement like that.
    One advantage of the bag is that you can use it like some sort of rodico (minus the sticking part) and press lightly on the components at hand so that they won't move or jump around.
    You can already insert one of the feet into the recess by sliding it in/underneath and when you do that try to position the 2nd foot into the spaced out slot that allows it to fit inside/underneath the incabloc system. Then rotate and do the same with the third.
    That's how I did it.

    Honestly, for jewels I think you need a microscope. That's what I would use and I do plan on buying one soon.
    You can find cheap usb microscopes for as little as 10$ and they seem good. They don't have a very high resolution but still usable.

    The movement that I had had a different spring than yours. It was shorter and it was flat not rounded.
    Something like this.

    Might be a good idea to check that the one that you have is the right one.

    The spring is supposed to hold that small part/pivot next to it in tension which in turn will hold the calendar wheel in splace.
    It'll prevent it from moving in the wrong direction but allow it to rotate in the right direction.

    Chopin reacted to jdm in Seen here first: the new Witshi audio-optical, and PC analyzers   
    The Witschi representatives in Hong Kong are really nice people, today I visited their booth at the Hong Kong Watch & Clock fair and they gladly showed my the first ever analyzer using optical data acquisition (as well acoustic), the Wisioscope S. The balance wheel movement is captured by a lens ans sendors, that works even the movement is in a plastic case. After processing it's displayed together with the audio in an "overlapped" format using different colors for the two channels.

    In an another display mode (I suppose there are even more) the display shows frame-by-frame images from the high-speed camera for visual analysis, I suppose to diagnose issue like pallets depth, lift angle. The machine is hence able to accurately display the latter for any watch mov.t.

    The apparatus is meant for manufacturer's R&D centers, and cost in excess of 10,000 CHF.
     The other new product is their PC-based timegrapher, called CronoMaster. Sorry, no pictures for this one, physically it consist of a nice multi-position mic with USB interface for a Windows PC or tablet. I haven't played much it but it looked nice enough. Full specs and screenshots on their websites. Cost is about 2,000 CHF.
