Elgin 292 movement pocketwatch

always nice when doing a discussion is to give us a picture so we know what were dealing with. So for those who are not familiar with the 292 it's a seven jewel American pocket watch like the drawing shows below.

American pocket watches can present challenges. For instance manufacturing tolerances were that every single escapement is adjusted for the individual watch. This means if the component is having an issue it's best to fix the issue if at all possible rather than trying to swap for another part that will have to be adjusted anyway as it will not be a drop-in replacement typically. Especially with the key component like a pallet fork.

Then we get the other problems especially if the watch was made over time which is variations. Like the pocket watch database indicates two separate pallet forks but doesn't tell us why?

the problem with the pocket watch database for parts is it doesn't give us the whole picture like the notes CF to go to another website for you get the notes to find out why you of variations and you need your serial number figure out which version you supposed to have.

Hi I'm experiencing this on my timing machine reading can this be caused by the beat error?

like everyone else the beat is not the problem. If the numbers can be believed at all which I'm suspicious based on the graphical display your amplitude is way too low. But no matter what you have to clean up the mess on the graphical display looks like one side of the escapement is definitely causing an issue and very likely other things.

      Help for a novice - fused spring bar

      By SamLiddle · Posted

      Alright, the job is done. I first filed down the stubs flat. I then used a Proxxon hand drill first with a 0.5mm bit to score a point to work from, then a 1mm drill bit to properly drill out some lug holes. I just went slowly, checking the depth as I went. I drilled the inside of the lugs, leaving the outsides unblemished. I was worried that drilling at an angle might be a problem, but it turned out fine. Lug holes don't need to be very accurate, so it was actually easy to create holes to easily accommodate a spring bar. The result is a 'good enough' outcome that worked for me. Thanks for your help everyone, loving the hobby so far. I learn so much with each project.

      Welcome to the forum. Yep not a cheap hobby by any means , Ali Express, the Chinese Amazon has some decent tools but should ask the members their thoughts before purchase.  A little reading to help you along. TZIllustratedGlossary.pdf

      Elgin Excelle 17j auto

      By Razz · Posted

      Just picked this up earlier today. This find just about epitomizes vintage watch collecting for me and what really keeps me going. Hit 2 antique malls today and saw a couple of pieces at the first one but just nothing that I needed. At the second one saw a Accutron 218 but it was 20 minutes behind the actual time. These "malls" have numerous booths of a variety of sellers who likely go in once or twice a week. Considering that that watch should be within a couple of seconds a month, I figured it hadn't been phased so passed on that for now knowing it would need work to run correctly and the price tag. Then I found this Excelle in a display case. I never heard of the brand, but in was an auto and had a little heft. It turned out to be 40mm lug to lug, 35.3mm case width, and 12.3 mm thick. On the spiedel once size fits most flex band. At $10.80US with tax I immediately pulled the trigger with nothing to lose. Before pictures: I spent a nice 30 minutes taking it out of the case and running that through the ultra sonic replacing the crystal and gasket and recasing, but spent five minutes first getting it running close on the timegrapher. Had a new crystal already in stock. I probably could have sanbed and polished the old one, but for $3 there is nothing like a new acrylic that makes a watch pop, in my opinion. The caseback gasket was hardened and just glad it wasn't tar. Changed that as well. Here is the after Pic on a temp black strap while I decide on a leather or steel bracelet. An added bonus was doing some research and finding out the Elgin connection and the movement is a PUW 1563T which is German I am pretty sure and probably why it doesn't say Swiss made on the dial. This movement is supposed to have a hack feature and quickset date by pushing the crown. But neither of those complications seem to be working. Not sure if the stem is cut too short because there is no gap for the crown to move. Either way at some point will need to be serviced and check the keyless works to find out what is going on with the quickset and hack of the sweep second hand.

      On the link that I posted, one of the watches has no crown and another has a crown that is not square to the case. Does a broken crown signify that the movement may be quite corroded, hence the stem has broken, and does the bent crown simply signify that the stem is bent? Unfortunately as the seller has a bid on the items, he is now reticent to prise the casebacks off in case he damages something. The seller did reply with this email though. Hi again Michael - brief descriptions; Oris x 2, dials and hands ok and they set ok and one I just wound and it has been running for a few of minutes as I write this response. Rocar, dial ok no crown. No name dial no good and can't pull crown out to set. Roma dial and hands ok, I think it is pin pallet movement. Unicorn, good dial and hands and plexiglass ok for age. All cases and plexiglasses show wear except as mentioned. I have no idea what movements are fitted or condition so please if you do consider bidding, please do so accordingly as I don't like to disappoint my customers - regards and thanks again for your interest - Jim
