Looking for a part! In need of help

Question

Hello.

I am now working on a vintage "trench watch" movement from 1910s that I mentioned before with a question regarding identification of the movement.

(I still haven't got the exact ref. of the movement.)

As I was disassembling the movement, my screwdriver slipped and broke one of the parts that function as a spring for the click.

I tried looking for replacement but I am not sure what I should look for.

Also, one of the jewels on the  wheel bridge is broken so I need a jewel as well. 

Could anyone advice me on how to find the correct part for click spring and the jewel for the wheel bridge??

**Could the click spring be put back together??

Thanks. You are always of great help.

Hello. I think the diameter of the movement was around 27mm. I will give you exact measurement when I get home!

One of them is 25 mm . But they both have the same spring. So hope the spring is the same. Have some EB springs to . If the AS is to short one could modify the spring from one of those movements.

It would be tricky to repair the click, but not impossible.

It wuld need to be silver soldered (Hard soldered) at the break, but done in such a way you don't heat up the whole click as then it would loose its spring.

to be repalce the jewel you would need a jeweling tool.

You need to measure the diameter of the pivot that goes through the broken jewel and the hole the jewel is in.

to measure this you would need to remove the jewel. If the jewel comes out in you part you can just measure the jewel, then you would need to find a Seitz jewel that is the correct size. If you cant find one exactly the same find one with the correct pivot hole and dlightly larger diameter. You would then need to use the jeweling tool  to ream out the hole to the correct size and fit the jewel.

Mark has done a good video on this in the past.

Unless you plan on taking up the hobby serious a jeweling tool will probably be beyond what you want to spend, even a second hand one.

Well that is a good news! May be I should check on Mark's video.

Hope the jeweling tool is not super expensive..haha..

Thank you for your helpful advice!

Hello! I got the measurements. The size of the movement is 29mm in diameter and the spring is about 14mm in length when measured from one point to another. I want to purchase the part if the size is appropriate.

The one i have is 13,5 so should work. On your watch it looks kind of long. Send me a PM .

      Hello everyone. I have a really sad story and I am a complete amateur. I am a machinist for a living so I thought I would give a crack at making a frankenwatch, however it did not go as planned and now I have a movement with subdials that don’t work and a whole lot of parts and money invested and I don’t know what to do. I need the help of a professional. The donor movement was a NOS, new old stock, and was running perfectly, however I messed up almost everything attempting to make this watch. I will happily ship all of the parts needed to complete this watch and pay for any repair that need to be made and for the return shipping. I need the help of a professional how can repair and assemble the watch with the parts and return it to me. I will pay for everything, the labor, replacement parts, return shipping, I just need someone’s help. 
      Details about the project: 
      movement: valjoux 7733
      dial: vintage NOS angelus chronograph dial
      case: custom machined case 
      crystal: plexiglass

      Hello forum, this is my first time posting.
      I found my great-grandfathers Timex maybe about a year ago, and to my dismay, it wound right up some 50 years later. From what I can tell, it looks to be a viscount model maybe pre-1960s? Possibly closest to a model 31 movement. My area of expertise is really limited to owning battery operated watches, so I'm hoping someone could help.
      I was using my hand to hit a wrench for my car and I didn't even notice I had my watch on. The movement stopped and from then on it's been acting funky, basically just stopping randomly throughout the day, but then restarting. When I take off the case and manually wind the rotor with my fingers, it will continue to run for quite some time, but once I try to wind it with the crown and stem or maybe even shake the watch it may only last a few moments.
      I hope someone may be able to help me diagnose some potential sources of this, since I would love to keep wearing my great-grandfathers watch. I've attached pictures too

      I have a seiko 7548-700f that I bought at a flea market for 15 dollars. Very beat up. Heavy scratches on the back near the lugs. Looks like the previous owner didn't know how to take a case back off properly. Last year during a battery change the screwdriver slipped and i hit the coil block. I managed to replace it without trouble. Starting a couple of months ago it started losing time. LOTS of time. I would take it off overnight and in the morning it would be 5 hours behind the correct time. Happens no matter what position the watch is in. I suspect that this is because the hole for the center wheel is not circular anymore. I know this means I need a service but I can not afford one. I am in highschool with no job. I have posted similar threads to this on several different sites, but no one is helpful. They tell me to get a job or to just pay to service it. What should I do? Should I learn to service it myself or is it even worth it?

      I have a watch that I am fixing up for myself. After lots of research l, I concluded my watch is a 1960s Hamilton Stormking VII. As my watch needs a new crystal I ordered one from ebay that is for a Hamilton stormking VII. When I got it in I immediately realized that it doesn't fit. The replacement seems to me about 1mm larger than the original. (I dont have a caliper). Is this even a Hamilton Stormking VII? Or did I get the right crystal but I have to modify it before it fits?

    • I'm following this. Case restoration is most important its knowing when to stop as it is easy to damage what has built up over the years. 
    • If you look at the link of the pocketwatch database for the serial number and you go to the parts list you can go to Springs and I snipped out an image. So we have an Elgin part number and a strength as an added bonus you click on the part number and you get this link https://pocketwatchdatabase.com/search/result/elgin/9785822/parts/catalog/X791/250 Fortunately it looks like that particular hairspring goes in a lot of different watches. That's the good news the bad news is we still have to find one and you're going to have to play with the screws to bring it in to time. When I get a chance I'll go look at my Elgin parts catalog and see what it says about the hairspring if there's any other additional information. Then that is assuming that it just needs a hairspring and that it doesn't have a broken balance staff more than likely it's going to need a main spraying and if you're lucky that's all that's going to be wrong with. I don't like when parts are missing like any parts it suggests other things could be missing were not even right. As one of the cautions of buying off of eBay it might look nice and pretty in the picture but in real life that doesn't always agree with the pictures. On the other hand the watch that I bought that wasn't quite what should be scrapped for parts because I really needed one of the parts off the watch so it worked out at the end.    
    • Dr ranfft shows 18 size HS to have come both in flat and berguet. Will you show a side view close up of the balance? I suppose you can go by serial No as well to find out the hairspring type.  Building the complete balance on these is challanging. 
    • In case anyone is having trouble curing their UV cure products, check the UV curing light. Most nail curing lights are using UVA leds with a wavelength of 365 to 405nm. These tend to have a low output and some manufacturers apply higher currents than recommended to increase output. This unfortunately will shorten the lifespan of the LED. The bad news is it will still lights up but the useful UVA part of the spectrum is gone. Hence your varnish or glue won't cure properly. Another problem is using a dental curing light for curing UV gels. Our dental curing lights are actually using blue light with a wavelength of 450nm. There is absolutely no no UVA. It is designed to be safer for eyes. Hope this info helps.
    • Yes that is a problem but unlike when I try to point out that swapping hairsprings is a bad idea and it typically falls on deaf ears on this group this is an American pocket watch. Providing nothing else is wrong and if the hairspring truly is missing it's not like it fell out all by itself which then makes other things suspicious that they could be bad. But providing it's the only thing that's gone missing in this watch it can be replaced. American pocket watches were some of a few watches that hairsprings are available as a separate component. Although finding one and the associated timing screws to bring it in to time will be an interesting challenge but not impossible. Then it's a shame it wasn't a 16 size? 16 size is a much better watch to start playing with 18 size has some interesting challenges but still a watch somebody can still taken apart with caution and before the original poster does so I will explain some cautions before taking it apart to avoid unpleasant surprises and damage.
