Greetings Watchmakers!

I must ask not so much of identification of movement, but first asking if it even possible to fix this movement.

To give optimal verdict, problems with it are written here:

1. Movement was broken out of case. Dented case in one point. Movement still sits fine in it. 

2.Dented balance wheel

3. Balance wheel missing rubie

4. Pallet fork stem with broken pivot

5. Missing parts in key less mechanism

6. Missing intermittent gear to canon pinon

7. Missing minute and second arms. 

8. Back side missing crystal. 

Although all problems (without maintenance and maybe main spring) are known, i wasn't able to find for 100% a manufacturer for this movement. 

Or caliber for that matter. Closest for my opinion are FHF or AS movements. Size 12s, 19 rubies, Balance wheel sits in bottom part, in opposite site of winding stem. 

Sorry for bad image quality. I know that daylight should be better. 

 

Knowing that, is there way to find parts for fixing this movement or should I put it as memorabilia in the drawer? Thanks for any advice.

I would consider this watch as 'easy fix' This is because usually I work on movements in much worse condition. The only part needed is the minute wheel, it can be found (if one have big collection of minute wheels) or made. The movement is FHF, but parts are not interchangeable, so no point to search for donor. Balance can be straightened, the stone(s) can be replaced, the pallet and balance staffs are routine task.

EASY ! 😲 This may be an 'easy fix' for a man of Nev's ability (and workshop), but for most it would be a challenge. 

If you could find a donor movement, it would not be difficult. But Nev suggests that this is not possible. 

Unless you want to spend quite a lot on getting it fixed, putting it in a drawer might be the best option.

Hi Nev. Just out of curiousity: how would you go about straightening the balance wheel? Would you use pliers?

My game plan would be to remove the screws, machine a cone shape with a slot (where the balance wheel arms would fit in), fit the dent balance on it and then gently tap it down until it is snug all around. But, being an engineer, I might be over- engineering it a bit.. Would heat be needed?

What you suggest here Case is the traditional way a jeweler would straighten out or resize a precious metal band ring using a steel mandrel

Hi Cees,

Actually just pressing with something round from inside against something, may be soft wood, is needed here. The 3 screws where the worst bent place is, need to be removed. Where the screw holes are, this are  weak places, so risk exists for the rim to break, but I have straightened even worse bents. This is matter of luck, and if needed, the balance rim together with the hairspring are to be replaced. It is good for one to have orphan balances collection  from which to choose one with proper size. This balance is bimetallic (steel/brass), but is not cut. I would not heat it, would just hope it will not break

So ideally it is fixable. Nice to know. 

Then eBay must be my best friend to look for parts. Or maybe You have some suggestions where to look for parts. BTW. Any ideas to what caliber this movement is? 

And how to fix pallet fork pivot?

Ah. But now you have the perfect excuse to get one 😉 

Seriously, if you're working on older movements, a lathe will often be needed/handy.

Seem so. Taking my  shovel an going to eBay for early name day gift. 🙂

1K63 metalworking lathe will be to much for fine pivots.

Right - I have been chuckling about this. It's like Gandalf telling all us hobbits down here in the Shire how easy it is to defeat a Balrog.

As I said, the parts of such movements are not interchangeable. I doubt if this movement is documented with specific caliber number.

As EU still exists and postal services within are easy, You can just post the movement (no need of the case) to me. It will be no problem for me to repair  it and send it back. You can learn on other movements, like Molnija, for which parts are available. This one will not allow mistakes, so it is not for beginners.

By the way, the pallet fork staff is threaded, and it could be easier to repivot it.

Only thing to do is join the club and get that lathe that you want Michael 🙂

I wish. I don't even have space for a waffer thin mint. My work area is my computer desk. All parts, tools, books etc are on shelves around me. The room also contains shoes, bookcases, two guitars, and (this will shock you 🤣) a tumble drier 😲 as the kitchen is too small for it. So dust is a problem.

Lol Mr.Creosote.  it's just a matter of time Mike, not if but when that Ebay search begins 🙂.

      Calendar work certina 25-651

      By tonydagee · Posted

      Hello all, just disassembling to service, but I can’t figure out the working of the calendar work…it’s not operational the jumper and spring are ok, but the operation of the driving wheel has me at a loss. I can’t see a cam to drive anything. Is something damaged or missing? Help please!

      Unusual Seiko dial damage

      Believe the relume (not a fan) was done a long time after the damage.

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
