My new victim


Ammar

Recommended Posts

Hello everybody

I got my self this ladies watch to play with, I hate ladies watches but I liked this one, it's barely running I think it just needs a good clean the proplem is this is the first time I come across this type of balance jewel assembly and I'm not sure if I should take it apart clean it and oil it I've seen it on youtube but I've never done it.

You think I should give it a try and risk ruining the movement?

Hi Ammar  nothing ventured nothing gained, Granted they are more fiddly than gents watches but the same rules apply. Document what you do (photos) at each stage and take your time and most of all be carefull,  They are quite a bit smaller therefore finer engineered and by such easily broken, but having done it and got a worker the experience gained . is well worth the effort    The last one I did was ladies ball watch the size of a marble with a broken balance took a day or two but worth the effort.      wish you good luck.

Hi Ammar, I preume you are talking about the jewel assembly, no shock protection just end stones. Its easy if you go about it the right way.

1- Unscrew stud screw, push on stud a little to make sure its loose enough to come out, all while the cock is still on mainplate.

2- Take balalnce& cock assembly out, flip it over and lay on hard flat surface with the balance on top, turn the boot to release the hairspring, You can flip the cock over again so balance would be dangling down, hold the assembly about a CM or less above bench, push the stud out, balance falls out, one CM drop would not damage the hairspring,specially if dropped on tissue paper.

There are two little screws holding the end stone plate, break easy, I soak the cock assembly in coca-cold over two nights, coke will penertate the screw thread so screws can be remove with incredible ease. Dress a driver blade for perfect fit into slit of the two screws.

This method is prefered since you can check the jewel and end stone as well as good access to peg. 

Good luck.

Done loads of very small ladies watches.  Basically endorse comments above.  Only advice I can give is take great care when handling the balance as the hairsprings are extremely delicate and very easily damaged (a super sensitive hand is required to correct !!).

The spring needs to come off to get sorted out.

Insert a safety razor into the seam between the collet and collet seat, work you way around the staff to open a gap. The sides of the razor are thicker than the blade, drive the side into the gap to widen it more, by then you should be able to get a thin screw driver blade into the gap or just wiggle the razor to remove the hairspring, you should have some sort of area, a tray or something to drop the hairspring on, so you can find it right off, as you would have a macroni hairspring if you swept the floor to find it.?

Next clean the hairspring in lighter fluid, then spread a white sheet of paper on top of a flat surface, drop the coil on it, you can see the coil and circles in contrast with the white, sort the coil, I know easier said than done.

Do I have a good chance in you opinion? I've never done this before so I'm scared to do it, I have a couple of mangled spare hairsprings I think I'm gonna practice on them before I try to fix this one

Hi Ammar  managed to dig up a little information on the dogma make The following likn will explain a little more   https://chronotimepieces.com/dogma-one-of-the-many-that-didnt-quite-made-it/

Thank you, you always help with links anf files and information I'm gonna call you The Info Guru ?.

Have you worked on a Dogma before this movement looks and feels high quality at least compared to the crappy movements I usually work on.

Hi From the information I have looked at Dogma used quite a few eubauches movements across the range, so from that I gather they are typical swiss movements and probably worth doing if we can identify the maker. The mark an cal would most likley be either under the balance or on the front plate under the dial.

Ofcourse you do, oh, I would unpin the hairspring from the stud while stud is in its holder arm, just get the stud out of your hair. 

Sometimes I run a pin through the collet hole and pin the coil onto the paper or cardboard, keeps the coil from moving.

Never met anyone with 100% success record, you might mess this one, so what.

I, also, think you have a good chance.  I have gotten lucky with sorting out springs before.  You just learn not to be rushed; move carefully and calmly; it will take as long as it takes.  Practicing on junked springs is a good idea to get a feel for how it will go.

And like Nucejoe said, you may never reach 100% success, but you may get pretty good.  So it's always worth a try.

    • Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy
    • I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!
    • Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.
    • So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
