Hello everybody,

Last year I posted about a Dogma ladys watch that had a bad balance.

 

I've been trying to find a balance ever since with no success it seemed to me like it's impossible to find a parts movement with a good balance  I literally have like 8 movements laying around with broken balaces.

I finally managed to find a donor movement but I am scared of taking the balance off and oiling the end stones and messing up the balance again, what would you do if you were me?

Also, on the new movement, the main bridge is jeweled at the second wheel hole but in the same time I like the engraving on the original movement, Should I go with the jeweled bridge or keep the one with the "Dogma" stamp but no jewel.

(I know that I can buy parts off ebay but the difference in currency and shipping would cost me more than what I've paid for the 9 movements combined together)

Hi Ammar, 

 These two variants differ in that the old one has fixed stud holder and the new one got mobile stud carrier ( beat adjustor). I go with the newer version and replacing the gears bridges should technically make no difference. 

Good luck.

Yup, the mobile stud is a plus, I didn't notice it when I bought the watch though, I was so excited to notice tbh, the difference between those two movements is that the old one is FEF 250 with a sub seconds hand an the newer on is FEF 250-1 with no sub seconds hand, and as pointed out by you looks like the stud carrier is another difference between those two. 

Oh and also the capped escape wheel and jeweled second wheel, it's a nice movement overall.

Eyup Ammar when you say broken balances what are we taking about ? 

Broken pivots and mangled hair springs, it's a mess and I;m not the one who caused it I'm just unlucky.

I think you are saying that I should've  put a hair sprig from one movement on a balance wheel from another which I considered but all the balance wheels I have are broken, the mind boggles.

I'mnot sure I understand what you want to say.

Sorry ,   I was talking about which one of the two watches I assemble to a complete watch.  if the subsecond dial looks better I assemble that to a watch, by the same token I go with the center second if its dial looks better.

All the staff pivots are broken ?

As Joe and Klassiker have said, the hairspring should really stay with the balance wheel. But then you will have to buy a new staff and fit it. The hairspring is matched to the balance wheel, swapping them around will give you timing issues. But this may still be better for you than changing a staff.

Yes The sub second dial is way better and that's what I used actually, I serviced the movement yesterday but the hair spring is bunched to one side even though the coils look absolutely fine when its off, so I'll have to investigate that on Monday.

Change the staff on one of the balances with a good hairspring. Don't interchange the hairsprings and balances if you can avoid it.

Yea I know that but I was thinking of it as a last-ditch effort if I don't manage to find a balance complete, I cant fit a staff because I don't have the tools to do it unfortunately.

And yes all the staffs I got are broken it might be a problem with this particular movement I'm not sure and couldn't find anything online about it, it's a nice movement though I enjoyed working on it even though I absolutely hate ladys watches.

 

And by the way, if anybody needs parts for FEF 250 movement apart from the balance just let me know I have loads of them.

Around 8 i guess.  You were determined though i would have stopped at 3 😁 

Well here's the situation, I'm as stubborn as an old mule so if I put something in my mind it's going to be done somehow. I also was planning to give this watch to my mum but I got her another one so I told my fiance that I have a nice vintage watch for her and you know women she has been nagging me about it for a while so I had no other choice.🤣

      Epilame / Fixodrop

      By Knebo · Posted

      Yes, I was referring to the (jewelled) gear train with HP (most of the time, I use 1300, but when Rolex says 1000, I'll use 1000).

      I suppose it would depend upon what your lubricating with those? for instance what does the manufacturer say about those lubricants? I have a PDF from the manufacture and a rather peculiar statement found on the bottom of the chart. my suspicion is the reason the recommending would be without epilam the HP oils like the spread except when they're in Ruby jewel's with steel pivots. tableEN lubrication 2020.pdf

      Is this a 'hack' ?

      By oldhippy · Posted

      These types of hairsprings become weak with age and very fragile. Which I expect it is that giving you trouble, and that wheel is not the correct one, if it were not bent I don't think the movement would run as the teeth are not the correct height. The problem you have is price which depends on you. It can be repaired but is it worth it to you, because there is little value in the clock. A wheel can be made and hairspring replaced. Or hang on to it and keep looking on ebay which is your best bet for replacement parts or even a complete movement but it will be like finding a needle in a haystack.

      Epilame / Fixodrop

      By Knebo · Posted

      I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.
