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.

First of all we need to id the movement. Could you tell me the size of it and could I have a close up photo of the movement both sides, dial off so I can see the keyless work. Sorry but my eye sight is not so good.

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.

      Anyone know a supplier that would have orient watch parts. In general orient doesn’t supply parts I guess and it’s been hard to find on eBay. I have an EM60 repair. The crystal was damaged and whatever damaged it burned through and burnt the inner bezel and I cannot find a bezel with the same markings. Any help would be awesome.

      Hi folks, just discovered this site tonight.
      I am mostly a newb, although I have experience with smallscale work from electronics.
      I have recently gotten into watch building, not from scratch mind you, I buy the movements...
      I recently came into a Luminox, with a Ronda 515 movement in it.
       
      The movement runs slow with a brand new battery.  I figured for $20 from Esslinger, the easiest fix for me at my level of skill was a new movement, rather than disassembly,clean,lube,re-assemble.
      So, I bought the movement.
      While trying to remove the crown from the stem, I learned the quality of the loctite/cyanoacrylate/whatever that Luminox uses to fix their crowns to their stems.
      *sigh*
      does anyone know where I can buy Luminox replacement crowns?
      I have hopes that I can remove the stem fragment from the crown, but those hopes are quite small.  I only have about .200 - .300 thousandths of the stem protruding from the crown.
      Yes, next time, remove O-rings, then apply heat, THEN unscrew the crown.
      Having problems uploading a photo of the crown.
      ANY help or ideas would be greatly appreciated!!
      Thx,
      Bob

      Hello Everyone.
      I need some help with repairing my Emporio Armani ar-1922.
      I've watched some videos on YouTube but none of them resemble the movement of this particular watch.
      My first problem is removing the stem/crown. I cannot see anything which looks like it will release the stem and I don't want to poke around inside it any more for fear of creating any damage.
      Any help will be much appreciated.
      Thanks.

    • I knew that Ronda offers Swiss made movement and Swiss parts movements. Typically the gold colored movements are Swiss made and the silver are Swiss parts. Out of curiosity, I popped the back off and.... Ronda 515... Silver plates.... Swiss in spirit only, lol. Thanks again @yankeedog
    • Well  my Florida brother. I hate to burst your bubble, BUT. Your pro diver  may or may not have a swiss  movement..most likely  it is a ronda 515...which may or may not  have come from Thailand. Ronda,a swiss  company  outsources there.some 515s are swiss,some are Thai. With invicta  it is really  the luck  of the draw. I like  your kirovskie  idea. Just be aware that that watch is not shock  protected..so you can NEVER  drop it.A quick  look  at them online reveals  a movement  that I think is a poljot  2409 with  without  shock protection...these movements  run well  for  a very long time. A have a few that  came in cheapo sixties  watches,that  run as well  or better  than  my cheapo swiss  watches of  the same era.
    • I just got this one and of course the crystal needs to be polished out, but the question is what battery did it take and how is it supposed to stay in place? Is there a battery holder missing? I can set a 39- negative down on it and press the back on carefully and it will run since the positive contacts the case, but surely that isn’t all there is to it. Has anyone else seen one like this?
