Hello,

 

I have just disassembled vintage pocket watch (Tsilla) which is my first attempt to this hobby ever. I have succesfully done that and found issue with balance - balance staff pivot is broken. Also, during maneuvering with parts hairspring pin (small brass one) flew away... 😞 I have ordered spare hairspring pins, but I wonder how to find replacement balance? Or can I fix it with simple beginner tools? I do not even know how to properly find a balance that will fit my watch.

Thank you all for help!

 

PS. I think I like this hobby. 🙂

 Caliber No is traditionally stamped on the movement, usually under balance. You need a staking set and plenty of practice restaffing a balance. See vids by Mark lovic on youtube.

If available a balance complete is your best bet for now.

If you still like this kind of work, even after losing a tiny part and seeing a broken balance pivot, then surely it was meant to be.

May I ask for pictures of the movement and especially the balance and its pivot?  We can help much when we see them.  The best and clearest pictures you can make.

You will see a lot of broken balance pivots in this line of work.  It is good you are learning about them now.

Let us see pictures and learn more and we will help how we can.

Hello, thank you so much for taking time to help me! I do really appreciate that!

 

I have made couple of pictures, however I am not sure if it helps as there is nothing really stamped... 😞

Balance wheel is smooth, there are absolutely no screws on it, I will be able to make more pictures later on. As staking sets are expensive, I guess I cannot really afford one now. I though of finding a watchmaker locally that would be able to restake this balance? Rest if movement seemed working while unwinding mainspring. 🙂

 

Also, if you know anything about such Tsilla pocket watch do let me know as I have googled and found nothing.

No trade mark, will you put all bridges back on the mainplate, someone might tell by the bridge layout.

Hello, I have managed to reassembly whole mechanism, clean, oil and lubricate it and... it works (beside balance...). 🙂 I am really happy as this is my first watch ever taken apart and reassembled.

 

Posting pictures of mechanism how it looks like and front so maybe someone recognizes anything and helps out... Thank you!

 

Also, any other sub-thread I can try to ask for identification?

 I still have no clue dispite the image of bridge layout, didn't think you'd have the whole movement back together before we see an image of the keyless. If you took pix as you disassembled, a picture of the keyless helps.

 In case it doesn't get identified, its down to removing the staff and measuring its dimensions.

You shouldn't attempt staff removal without the proper tool.

Oh, you showed the keyless profile above, will check Dr ranfft and might come up with the caliber. 

I can try to open everything again to show you complete keyless, I will try to find some time. Thank you so much!

No need really , can clearly see the profile in pix you have shown, I must be doing wrong in my search or Dr ranfft just has not listed this one. 

Many ways to conduct such online searches.

One of the ways to identify watches that are unknown is the look in the material catalogs. They have a system sometimes called the fingerprint system. The visit we need the diameter the movement measured on the main plate on the dial side. Yes I know you have a pocket watch but it really helps to narrow down the exact size. Then we need a picture of the setting components found on the dial side. The unfortunate problem with the system is the earliest book I have is 1951 I don't know how far back they go but they don't go back to American pocket watches for instance. Then there's some other books in the 60s and early 70s so it has to be within a relatively narrow window of time. Yours looks modern-ish another was it doesn't look super vintage maybe we might find it

even if we don't find it another way to do some of this would be to take your staff out we measure that and we look at a list of staffs by sizing yes they ask he have something like that and see if you find something close. So in addition to your staking sat you also need a watchmaker's lathe. This is why typically beginners do not do staff work the outlay of expensive tools and knowledge of using them isn't usually what beginners do.

You haven’t included a picture of the balance, but that looks like it has a cylinder escapement. In which case you may be able to push out the old plug (tampon) which has the pivot on it and push in a new one.

Easier said than done and whilst you don’t need a full staking set you will need to obtain or make some special punches, and a suitable tampon.

John has posted about these before here

    • Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with. I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements.  Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!
    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
