  1. My cleaner was in an area that offered no hope for finding such a small part. Plus, it was a hole-jewel, which I should think is in a brass setting, so a magnet wouldn't help much. That said, was rather surprised that the brass colored shock springs seem to have enough iron in them to be attracted to a slightly magnetized screwdriver. Either that or there was some other sort of attraction taking place. I sure seemed magnetic. So, yes, it seems that I could have used a magnet to find the shock spring I lost a while back. Thanks for your response. Cheers.
  2. I used this technique in replacing the upper balance jewels on a vintage Gruen. While the shock spring was of a different style, called Trishock, doing it under a poly bag is a good suggestion. I didn't place the movement in the bag, but sliced a plastic bag up the sides to make it single layered, and placed it over the top. It worked fine. Thanks for posting your technique. Cheers.

    Where to get parts

    You might be best off finding a parts donor. Otherwise, you can try Cousins in the UK to see if they list that part. The Bestfit number appears to be a #422 for the crown-wheel ring. So it might be that number, example: AS 1700 Bestfit 422. In the US, you can try Jules Borel or Esslinger. So you know, it's never easy. I think I lost one of those rings the first time I worked on a particular type of automatic movement. They look as if they are part of the plate, rather than separate, so they'll surprise you. I take it that you've already checked the cleaner, and are sure that it's not hiding in place? As I said, they do look like they're incorporated into the plate. Good luck.
  4. Well, where does the time go anyway? I hope everyone's been well since my last check-in. It's been a while since I've worked on a watch, but the weather's keeping me indoors more, so I'm back at it a bit. Thank you all for your help so far. I decided to take another go at this Gruen 505-6/ST 96-4 that I lost the jewel on. Using the working-through-plastic-bag and toothpick trick, I was able to get the upper Trishock spring in place, but the lower is still giving me fits. It just seems that the hole jewel I got from Cousins, Inca 711.11 either doesn't drop down far enough, or doesn't accommodate the present cap jewel. The combination seems to sit too high, which makes the angle too steep to get the spring arms in the recess. The top of the cap-jewel sits higher than the plane of the spring recess. Is it possible that the ST 96-4 versions that utilize the Trishock spring rather than the Inca, use different sized jewels? In looking for a parts movement, I notice that most of this model use the more common Incabloc shock system, not the Trishock. Any help is appreciated. Thanks ahead of time. Cheers.

    Elgin 462 Mystery

    The Chicago School of Watchmaking books/course has a section on keyless work that includes this style of Elgin. There are guys who sell it online in pdf form, or perhaps even give it away. It's worth having in some form if you are going to work on vintage American pocket watches. Good luck.
  6. Those are pretty generous prices for today's market. Real-world contemporary prices would seem to be, if we're talking naked movements in mint condition, might be $250 for Vanguard and $150 for the 845. Check out "Sold" Ebay auctions and you'll see something closer to real world prices. So yes, the Vanguard does have considerably more market value. All other things being equal, which they sound like they're not, repairing the 23J would be the way to go. You might head over to the NAWCC message board and find out which parts are actually directly interchangeable between the models. There are a few folks there who specialize in the 1892 models. I hope you get them both up and running eventually. Cheers.
  7. As beautiful as the '92 models are, being full-plate movements they do seem to get messed up by people taking them apart before they understand the pitfalls. Years ago I may have broken a pallet arbor on a 21J Crescent St. because I didn't know about the danger posed by the potance. Then, of course, there are a few different types of arbor to confuse the issue of servicing. Again, beautiful watches but best to buy them running well, IMHO. Unless you're are a proficient watchmaker, of course. I suppose the Vanguard may be a bit more valuable than the 845, but I doubt it's that much of a difference. I'm guessing that there were a lot fewer 845's than Vanguards. But, as most of us know, rarity doesn't always equal higher value. Best of luck with your repairs. Cheers.
  8. With all the problems the 23J has, I'd definitely work to make the 21J whole and running. I have a couple of '92's that are in need of work, but not that much work. Do you have nice cases for them? If not, the market for fairly common American pocket watches is pretty soft. And with naked movements it's even worse. The hunter '92's are generally more valuable, as well as those marked "Non-Magnetic" and "*Ruby Jewels". Good luck.

    Tissot 31.1 bumper movement mainspring

    Oh, and it gets better. Before ordering the second, and correct, mainspring from Cousins, I checked Ebay to see if I could get one. I searched for the mainspring part number. None were found. Minutes after completing the order, I was on my Ebay summary and saw that I had actually saved an auction for what at the time I thought might be the right mainspring, but wasn't sure. I forgot about it. It had another proprietary part number, so it didn't come up in my search today. But, it was the right one, and for quite a bit less money. I should just go back to bed. BTW, you have my blessing to enjoy a good laugh. Personally, if I don't laugh...

    Tissot 31.1 bumper movement mainspring

    Thanks, rogart63. As luck would have it, I went to Cousins to change the MS in my basket to the 1.60mm, and could swear that I did. But then, after ordering and getting the confirmation a few minutes later, it appears the change didn't take. Somehow the 1.30mm was still in the cart and the 1.60mm wasn't. Cousins is good as far as what they stock, but they have virtually no customer service that can help clear such things up before the stuff gets sent out. Maybe they're working 24 hour days there, but if not, they should have some method for correcting errors within a reasonable time. They don't have any such thing. If you order something wrong, it's a done deal and it's getting sent out. I ended up ordering the 1.60mm in a separate order, but I think it's going to be my last Cousins order if I can avoid it. The little voice told me to double-check before completing the order, but I ignored it. Bloody heck. Oh well, it's one of those bad-luck watches it seems. Thanks for you assistance. Cheers.

    Tissot 31.1 bumper movement mainspring

    OK, so I ordered an automatic mainspring from Cousins. The spring ended up being of a different size than the ones you (rogart63) used in your Tissot. The spring was also broken into a few pieces. I guess that's why it looked so strange to me.

    Tissot 31.1 bumper movement mainspring

    Thanks, rogart63! I'll probably order the part number that you used. Cheers.

    Tissot 31.1 bumper movement mainspring

    Hey rogart63. I hope that all of your springs are staying in place and watches keeping chronometer time. I'm back to this AS1171 bumper. I pulled the barrel, but not until after being lazy and stupid to lose the clutch spring. Lesson, don't take watches apart when you're preoccupied, or take it too lightly, ever. Anyway, is this what the spring in your Tissot looked like? It sure is odd. I've never messed with an automatic spring before so I expected differences, but this one looks downright bizarre to me. I think you may have mentioned that yours was in a few pieces like this one looks to be. Maybe it was in another thread? Anyway, I'd love to know if this is what yours looked like in the barrel before I place an order. All other input is appreciated. Thanks ahead of time. Cheers.

    Watch hand fitting tool

    If you're talking about the hand-held tools, I use two different ones. And I use them for pocket-watches and wristies. One has a red and black tip. The other has a white and grey tip. I just don't recall the sizes. The red/black one is larger and used mostly for hour hands and larger minute hands. In fact, I have used it for most things other than center-seconds hands, which I use the white/grey for. Good luck.
  15. Well, I engaged the hack-stop on the watch while it sits in a shared case with a few others. I like the idea of saving the battery, especially with a one-piece/monocoque case that is a bit more hassle to open and close. Mine has no battery hatch. :-( I checked it the other day by pressing the crown back in and it took off running, so it's still qualifying as a runner. Cheers.
