  1. @JohnR725 is right about that. The movement looks very much akin to the little grade 320, which Elgin used in lady's pendant watches, and having the negative stem like that, the case would have a sleeve to retain its half of the stem and crown. The kind of stem and crown, and sleeve, that you'll be looking for will be easier to determine once we know who made the case. In terms of pocket watches, Elgin made movements and did not generally make cases; you bought an Elgin movement, then selected a case from the jeweler's offerings and he would marry them together. As to wrist watches, Elgins
  2. Now I'm just gilding the lily. I'm putting the gold hands from one of my 16s Elgin parts movements onto the 339. They are sister movements with a great many interchangeable parts; according to Ranfft's site the hands will fit. I'm keeping the original hands in a little bag, but I want to use the gold ones. They're head-turners.
  3. Lovely Waltham that is! So then, seeing if I'm understanding you rightly, you took a glass vial full of balance screws and put them back into a balance wheel, and managed to poise it well enough to squeeze +/- 30 seconds per day out of the movement? Upon a poising tool which you built? That's not too shabby at all. I'd cringe at having to reassemble a balance like that, I admit. It had to have been slow going. To get it poised and trued and functional, that's good work.
  4. If the dial feet got sheared off, it makes me wonder how that happened without also damaging the canon pinion and center arbor as well (or maybe they are and we don't know). I'm not disbelieving, mind, just curious. I also wonder if it may be possible that, during a previous service, a clumsy technician broke the feet off and tried to hide his mistake by putting the dial back on with some sort of adhesive that has since degraded.
  5. Oooooo, you got the one with the nice wooden drum-shaped box! And the handle adjusts inward and outward to keep the barrel covered no matter which size of the shaft you're using. The learning curve with them is pretty short. You get used to them fairly quickly and it's easy to handle springs properly then, and keep them protected and straight.
  6. Yeah, it isn't in top form, and I had no desire to bid on it. But seeing that balance made me wonder what other interesting variations might exist out there.
  7. Working on pocket watches as often as I do, I picked up a K&D set (for a song too!) and have gotten much more use out of it than I expected. Its dimensions were laid out for the pocket watches of the era. So it works great for them. If you plan to work on that many such watches, you may wish to look for a similar set.
  8. Well, I've been known to make some pretty strong coffee, and also fortify it in Irish fashion, if you know what I mean.
  9. I have watched a video in which Mark did it. I understand the principles and I have the tools and the drill bits. But I have never done it, and currently have no pivot wire. I had planned to set aside some time to practice re-pivoting some old junk watch wheels and balance wheels, because I believe I may need to do so someday. I can tell you, it can be done. If you're not in a hurry to fix the watch, you can acquire what you need to re-pivot the staff: pivot drill bits, to start. I have a pivot polisher that is set up to take drill bits, in perfect alignment. But a small lathe is proba
  10. I was just drinking coffee this morning and poking about on Ebay...when I happened upon this movement. The seller didn't seem to know much. I can tell it's a Swiss bar, key wind & set, no idea of the maker. But I have never seen a balance wheel like this. Ever. Has anyone on this forum seen one like this? I'm curious to find out more. I wonder if there is a mechanical explanation to this design, or if it's done purely for aesthetics. It's fascinating either way. And it looks like the largest diameter they could cram in there too, which would have several advantages.
  11. How about that? Yeah, being a Waltham, it is more likely to have a hole than a tongue. I was about to wonder how they got that spring to work before, but we don't know if they did. Now I'm not surprised that the tongue broke off.
  12. There is a "tongue" riveted to the end of your original mainspring (which would catch the hook on the inner surface of the barrel) and that tongue has cracked in two. That is one cause for mainspring slipping.
  13. Yes, thank you John. Pictures really are worth a thousand words, particularly in the subjects with which we deal.
  14. Some have a little lever at the edge of the dial-side base plate which, once the movement is taken out of the case, will be released to project outward, placing the movement in "set" mode. The clever and beautiful way these levers and linkages operate is one of the most captivating things about these old mechanical watches, for me anyway.
