  1. My wild guess is that it's lume. It's interesting dial in that they printed the outline of the numbers. This would allow somebody to hand paint the luminescent material on and know where to do it. It'd be interesting to knowing the time frame that the dial and/or watch was made. I'm guessing because it says the word waterproof we can narrow it down for that. Finding a modern luminescent material that's darkening colors going to be interesting. Then because this is a holder luminescent material it's probably dark because it's radium based. But you need a Geiger counter to verify that.
  2. One of the amusing problems in watch repair is its worldwide spanning a very large period of time. So conceivably perhaps unacceptable in some parts of the world those terms might have been common terms perhaps somewhere. Like the names of parts that can go by a whole variety of names depending upon when and where you're located. If that's what you're looking for you should a started off with a clock. Preferably a clock that doesn't have a mainspring barrel and things can be much more dramatic when the power of the spring releases with no barrel to contain it. Then unfortun
  3. Notice the quote above rubbed in jewels or burnished in jewels? Plus look at the color of them those are natural stones they always have flaws in them or can always have. You need to look very carefully at the hole itself is it nice and shiny does the crack extended in such a way that you can see it. Look at the pivots do they have score marks where the crack scored cut into the pivot? What unlikely the answer is the jewels look fine at least from a bearing point of view and the pivots are fine. Then notice the color the jewels which by the way can be any color but these are clear? Modern
  4. We rely on your eyes to make diagnostics but your eyes aren't seeing the problem yet. Could we have a picture of each of the watches looking straight down set it over the balance wheel. That another picture looking inside ways at the balance wheel. It's amazing how much energy you can lose at the hairspring isn't quite where it's supposed to be. In addition to all the things above but. Sounds like your gear train is free by your own description. So it could be related to the balance wheel. With no power at all the balance wheel should be very very free to move is it? In other words if you
  5. Background history of the watches? Were they running before you attempted to service them? From my interpretation of the quoted above you appeared to views the Springs that were in the watch? What color were they blue or white? What did they look like were they a really tight spiral or did it open up quite a bit. Even if they were set that means there were a really tight spiral you still should Be able to wind them up a little bit and what should run at least for a while not the problem you're having. Maybe you should explain your cleaning procedure and lubrication procedure?
  6. Are you looking for something like a technical communication? Or specifically the file I've attached? _c_t_ct_6498-1_fde_482382_10.pdf
  7. Here's another online distributor of watch crystals https://tiptopcrystals.com/
  8. always a good operating procedure before ordering a balance staff measure all the dimensions and compare if you can with the staff your ordering before you order. Then when you get the staff you also want to measure everything again to avoid unpleasant surprises down the road. then what's weird site below has two identical watches for the same number which represents the ligne size and then there's a third one that's a little variation in the height? which is why you have three staff sizes apparently. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Revue_
  9. these are equivalent to the number ithat you'd find other the balance wheel. It's the model number of the movement. Which should then at the above link that wls1971 gave you ESA 9162. the reason it has the reference to Bulova is that the Swiss attempted to get around Bulova's patent on their tuning fork watch they made basically an entirely new watch but somewhere they still had to give credit to Bulova for something. Then it seemed like we had just discuss this watch and it wasn't that long ago. I have a link if you scroll down the conversation you'll find the service manual and som
  10. I forgot for up above it would also be nice to have a picture of you holding the watch in the movement holder so we can see if there was an issue with how the machines picking up the watch plus whether you've ever had this happen before?
  11. I have a link to a website below that you can use to convert your image files to JPEG which the discussion group can look at versus the file you have which the discussion group Process and most people probably can't look at it. out of curiosity which timing machine are you using? it would be nice if you'd wind it up again give us a photographs in preferably two positions. Either dial up or dial down and one of the crown positions like crown down fully wound up. but as a reminder fully wound up means you wind it all the way up but let it run about 30 minutes and then put it on t
  12. this is why pictures are nice it allows us to see things that maybe you don't see? casually your hairspring looks fine but? overlooked as it's part of the automatic winding your magic lever is not where it is supposed to be. I'm attaching a couple images one of them shows how it's supposed to be. then look at your image that I snipped out and added some lines in. They even made a nice hole in the plate so you can see that the magic lever is missing? having your lever on top of the wheel that it's supposed to engage with a cover plate pushing down on it probably not desirable.
  13. I was kinda hoping for the entire back of the watch case itself. But the case back was nice because we get a number from the number we get a picture.
  14. normally you don't find this in the technical sheets. For eta if you can find the manufacturing sheet that's where that would be. But I went through my computer to see if I had anything and I'm attaching something. Go all the way to almost the very back in and you get the technical drawings which cover the hands sizes. then initially the numbers look confusing until you actually look at the specifications and realize there are two separate second hands in the middle. the numbers above break down to hour, minutes. Second, the other second and missing is 20 for the little hand. then bec
  15. we really need the back of the watch case but it looks like a ring used to hold movements in.
  16. It's the problem with so many things the lack of knowledge of what people are supposed to be doing. I suppose technically all lubrication's are breaking lubrication's. That's because they have surface tension but typically we don't think of oil and standard grease as a braking force. This means that using 8200 totally sucks is a breaking grease. But obviously some people don't pay attention to that. The modern schools are now using 9501 for the grease on the mainsprings. Which is interesting because they try to follow the modern techniques and the modern techniques are not to lubricate
  17. I'm willing to take the time to look up the setting parts to see if it exists in one of the older books of the fingerprint system of setting parts but I'm lazy and I won't do it unless I get a line size. The fingerprint system works best if you know what the line size of the movement. Than the problem for the older watches at least in the older book I have is that the most you might get is a name but see if the movement compares to who we think made it What's troublesome in this discussion is I thought it was a Swiss fake American pocket watch because that's what it looks like but? It
  18. A minor wrinkle in this discussion? For which I won't have an answer until I go to work tomorrow perhaps. Do you know this tool comes in two different sizes sort of? It actually comes in more sizes it comes in various heights for the various staking sets. Then the hole diameter that the punch goes into comes in two different sizes. One for smaller watches and a bigger one for pocket watches. Problem is I can't remember if the punch is different sizes or whether they just have one of those?
  19. I was looking for a tech sheets and the usual sources it doesn't seem to be available? It's the problem with a lot of the older watches they never got scanned their word enough of them or enough demand for somebody does do a tech sheet possibly. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Vulcain_120
  20. I have a link to their website. http://www.westendwatchco.ch/
  21. To me the movement looks cheap very cheap. It looks like a counterfeit American movement. Yes they really did Make imitation American pocket watches or make watches that were supposed to be American pocket watches way back when. Attached to that question I have a link. https://www.worthpoint.com/articles/jewelry/history-roskopf-watch Then it looks like I'm late to the party again as this answer was started before the reply just above. But even though you paid 400 I still think it looks cheap. Doesn't mean it's not a collectors item. Looking on eBay I see one that looks simila
  22. Not all mainsprings are coated some of them supposedly because of the alloy they don't need Teflon or anything. But you still caught with the same problem basically it's invisible. If you clean the mainspring and it had an invisible lubrication it now does not. The problem with invisible lubrication is you don't know it's there. Which means if you clean it you remove it but since you don't know if it's there or not that doesn't matter. If the mainspring has old oils are greases they definitely have to come off because they will be sticky. if you have a nice clean mainspring it sho
  23. A question that comes up all too often is problems related to hairsprings. Seems like a simple solution the hairspring is removable they can be swapped. But you're going to end up with timing issues each hairspring comes with its balance wheel it's why they're not sold a separate components they come together. I'm attaching a PDF it's not for your watch I want you to go to the very last page. The very bottom of the last page look at how they hairspring looks? Compare that with your hairspring they don't quite look the same. I don't think your hair Springs been destroyed I think it can be
  24. Can you see the stop works? A lot of this depends upon how to answer the first question? Depending upon things you may not build a access the stop works without taking the barrel out. Then it's all the more fun with the power off not impossible just more interesting. It's much easier to do it in the watch if you can. Then you can let the power off without removing to stop works it will just come to a stop of course. How much power is there depends upon who set it up. There's not necessarily a rule of having one turn it depends on the length of the mainspring the watch itself an
  25. It might be nice if you gave us a picture looking straight down at the chronograph with as much detail as you can. One of the minor problems with the chronographs are and it's mentioned in the manual not all screws are screws. Some of the screws are for adjusting things and if you rotate them without knowing what you're doing that would be bad.
