  1. Hello All I purchased a non working Waltham model 1877 grade PS Bartlett ser# 1998658. When opened it I was excited to see the balance was swinging freely however quickly realized it was not ticking. I am sure you guessed roller jewel was missing. I have watched a few videos and read a few articles and seems very difficult and requires a lot of patience but its not impossible and want to give it a go. I have all the tools needed the only thing I don't have is the roller jewel, one video I watch he went through a large assortment of jewel until he found the one that fit is
  2. Hi All Thanks I believe I understand, jewel hole 13 size does not mean you would pair with a .13 pivot shaft with a jewel that has a 13 hole it means that the jewel hole is .13 too. Which now makes sense with what I was seeing when using the jewel gauges. I won't/shouldn't expected for a .13 gauge to fit in the jewel 13 hole as it would be a perfect fit and is why a .11 pivot gauge did fit as there is clearance. So would I be correct in thinking if I have a balance shaft with a pivot size of .13 that the jewel I would want would be a 15 hole? JohnR725, they are Elgin
  3. Hi All I have a pocket watch that I am working on that I needed to replace balance shaft and the upper and lower balance jewels. Shaft has been replaced and both jewels are held in by jewel cap and screws so should be an easy replacement. I found replacement jewels on ebay they are the right type (fits in balance cock) but the wrong pivot size, I ordered hole 13 thinking they would be pivot size .13 however they are pivot size .11 (used a jewel gauge to check). When ordering jewels was I wrong to think hole 13 was pivot .13? Regards, John
  4. Hi All I have a newbie tool question. I think I picked up a good find on eBay for 40.00, I purchased a set of metric jewel gauges (SWARTCHILD'S) with only the .07 gauge broken. The question is am I using it correctly? I started doing some balance shaft replacement and learned real quick that same part number doesn't mean same pivot size. Most of the pocket watches that I have purchased with broken balance shafts seem to be missing both pivots so what I am doing (pictures attached) is placing the lower or upper jewel on a piece of rodico, using a high power loupe, holding gauge w
  5. Hi All I have a follow up to a previous post, below is link to post. https://www.watchrepairtalk.com/topic/14190-selecting-the-correct-balance-shaft/ With the help of JohnR725 I discovered that when ordering a replacement balance shaft you have to be careful as there can be more than one type/size per part number along with different pivots sizes. Long story short I ordered the correct shaft (elgin 861 NS P.13) and was successful at disassemble, replacement, reassemble. I have a couple of the same model pocket watches with at least same issue (bad balance shaft) can I repl
  6. Thanks everyone for responses and help, Nucejoe thanks for the lesson/education I just assumed same part number (wheel and spring) interchangeable. I went back and found original spring and what an improvement!!!! Still have some positional errors going to look into but feel I am much closer to getting this piece working, again thanks and sure I will be asking for help again soon. Everyone stay safe!
  7. Hi All Nucejoe - I believe I have the correct spring, the scrapper I got the hairspring from had same part number based on this website and serial numbers. https://pocketwatchdatabase.com/ Rduckwor - I tried what you suggested and unfortunately after 12 hrs the watch gained roughly 8 minutes. Things have changed a little and believe I might be in a better place or maybe worse hoping you can tell me. My replacement shafts came in and successfully replaced and reassembled balance so watch now has its original balance wheel however now rate is not registering at a
  8. Hi All Thanks everyone for their help, I successful replaced the balance shaft, it took me two tries however learn from my first mistake and now on to the next issue. Regards John
  9. Hi Hector, Here is the picture I believe you asked for.
  10. I need help diagnosing old pocket watch that is running too fast I will try to give as much detail as possible, this is a previously mentioned project WW2 Elgin pocket watch. Elgin Prod yr 1943 16s 7 jewel model 7 grade 291 Ser# 41375491 It was a complete non-runner when I purchased it, I found the following issues. · Broken balance shaft pivots · Bent Seconds wheel pivot · Broken top pivot 3rd wheel · Cracked balance jewel lower. · Broken crystal I have a couple of scrappers se
  11. Thanks again for the information, the long and short of it is I think I might have made a few missteps when I was trying to use parts from a couple of scrappers I had that i used pocketwatchdatabase.com helped identify. Looks promising as I found a good balance wheel, hairspring and shaft of the same part number and after cleaning seems to swing freely after mounted. I think I need the NS 861 .13 pivot shaft based out of what I was able to pull from the scrappers of same model and order one from ebay. I already purchased a K&B 602R that came with the balance staff remover s
  12. Hello all, Thanks for taking the time to respond hoping you don't mind a couple follow-up questions. Again very new to this, is there somewhere I can get my hands on an Elgin factory parts book or pdf or better yet a source were I could find parts books for all different manufactures? I might be getting into the weeds but I have a few of the same grade (which had the same wheel and shaft part number) movements and found two that appear to have good balance shafts. Overall measurement of original shaft with both pivots broken is 4.80 mm, haven't removed roller yet (tool co
  13. Hello everyone this is only my second post (1st in intro). I have a project pocket watch that I am working on (something for my younger son he like ww2 era ) lucky for me there seems to be a lot of scrappers out there (couple wheels had a bent or broken pivot) however not the greatest luck getting one with a good balance shaft. I would like to try my hand at balance replacement, I have staking set tool and other necessary tools, below are the pocket watch details. elgin 16s, 7j grade 291 model 7 Class 110 Man yr 1943 I found the manufact
  14. Hello everyone, I have always like to tinker even as a kid just never had the right tools, recently a friend and colleague rekindled my interest in watches (more the fix/repair side). Ebay is great getting everything from scrappers, fixer uppers and tools. I have had pretty good success with tear downs and repairs (haven't lost any parts lately), I enrolled in Marks course (finished 1 & 2 working on 3) and looking on increasing my knowledge in skill with watch repair.
