I am working on a Revue 30.1 which has taken some proper mechanical abuse!!!!

 My first clue was the crown would not turn! I looked further and found a tooth missing on the winding pinion! Then all the teeth on the clutch wheel that come in to contact with that broken tooth are all gone!!!! I've gone no further in yet as this was scary enough as I've just noticed also that the centre post which the winding pinion rotates around has been excavated through high friction to about a quarter of its width on one side! The very top & bottom of this post are OK but the excavation is to the middle area. My question is, can anything be done about this post? 

 Many thanks all.... David

We always love pictures here. It makes it so much easier to solve a problem if we can actually see the problem even if the description is interesting in your case, by the way the missing teeth Are they floating around in the watch? Usually when things break off they unfortunately stay in the case to cause more problems.

Hello, yes. Here are a few pics. I may of got a few technical names wrong in my last post! I am stripping this movement completely down so any small bits will be got rid of. Thanks for your swift reply...

 The teeth on the sliding pinion/clutch wheel that come in to contact with the intermediate wheel are all gone(u may be able to see)and one tooth on the intermediate wheel has gone! But the post that intermediate wheel rotates on is where the excavation has taken place!!! Another quick question, if the wheel that the sliding pinion/clutch wheel locks in to is called an intermediate wheel? What is the similar wheel it locks in to next to it called? As when ordering parts I don't want to order what's not wanted.

many thanks....20220122_192448.thumb.jpg.7d3086b3134fa52713b83eca36104bc1.jpg

Revue 30.1

As you're new to watch repair I thought I'd point out something that this is not the watch you're working on? One of the problems with watches is figuring out who made the watch because you can't figure that out you can't get parts. The watches will have names on the dial is that who made the watch not necessarily. What about the names on the main plate necessarily the maker either. What about the funny little symbol next to the balance wheel I wonder what that means? Oh in order to see the funny little symbol we need to see the other side of the plate?

Then he had something interesting your watch wasn't made by who you think it was made by. Now the next problem is who major watch? Okay we figured that out but which model number is it and it's not 30.1 so it be nice if you would look for the model number? Typically it's found under the balance wheel.

Then if you don't have access to the watch's like I don't I have to make guesses? So I can Google your watch and find it at the link below which gives me a picture of the front side which gave me the funny little symbol so I can look up and see it was made by a wittnauer watch company. But which model is it? Now there is a way there's something called the bestfit book somebody will tell you how to download those for free. They have what's called a fingerprint system you look at the setting components and match them to your watch which does require you need to know the diameter of your watch.

To give you an example of what I'm looking at the fingerprint system you need to know the size and then made the figure out which movement you have tracked down the parts.

Of course the best would be as if you would find an actual movement number on the plate someplace

      Breitling Navi Heritage (ETA 2892A2) seconds subdial skippiness...

      By eccentric59 · Posted

      The fact that the seconds runner starts running smoothly when you engage the chrono seconds makes me think the clutch is out of adjustment. That's a guess because I can't seem to find out too much about the chronograph module Breitling used on this model. On other Navitimers they used the Valjoux 7750 which had the running seconds on the left where the hand was mounted on an extended pivot on the fourth wheel. It looks to me that whatever pinion is driving that wheel is skipping teeth. Given that Breitling (et al) is not forthcoming with manuals or parts, I would send it back and ask for expedited service. They should be sufficiently embarrassed to do that for you at least.

      First Project Already A Bit "Sideways"

      Looks like someone forced in a screw that was bigger than the hole.  You would probably need to drill it out with a tungsten carbide rod sharpened at the tip to look like a spade drill. I'll see if I can find a video on how to make one. Start with a 0.5mm rod, then work your way up in 0.1mm increments until the walls of the hole weaken the screw enough to break it up.  This is a very time consuming, slow process. You'll need to centre the hole properly and not deviate. WD40 helps. The other option is to abandon the hole and use a dial dot. As much as I hate dial dots, this might be the safest option for a beginner.  Ok, found it.

      First Project Already A Bit "Sideways"

      For those who are, curious I broke out the macro lens and took a few shots.  I'm attaching four of them: Image 1 is from the watchmaker's side and generally shows the problem area. Image 2 is a detail view of the offending dial foot hole (called out with the green circle), the tip of the offending screw (orange arrow) and the blue line indicates the approximate position of what's left of the head of the screw (determined by using an oiler as a feeler gauge to transfer that measurement to the visible portion of the plate.) Image 3 is looking down the screw hole you can see the head of the broken screw at the bottom. Image 4 is the same, but with less contrast to give a better appreciation of the condition of that end of the screw. I can almost convince myself that I can see the remains of the screw slot in the head, but I have to use alot of imagination in that exercise. Heard and understood.  There does appear to be a steel locating pin that can be seen in the lower, right center of Image 1 (right "above" the oval shaped slot that is to the left of where the pinion/clutch parts of the keyless works nestle into the plate.)  As I don't see a way to remove that I'd have to keep it out of the solution and have even contemplated dropping a little paraffin on it to give it a "rain coat" of sorts.  As I missed that before I did the closeup photos, I feel that I'm going to be looking at this plate in much greater detail to see if there anything else I might have missed. The screw assortments seem like a good acquisition.  The eBay seller who has the donor movements I was looking at never replied so I may just take a chance and get one of those as well a screw assortment.  They do seem like they'd be handy.  I have to confess that the idea of fabricating the needed screws appears to some deep part of my soul, I also have to confess that I do not yet have either the equipment, or the skill to use it.  Perhaps one day, but that day has not arrived (and I have alot of pricey bits and bobs that I will likely need to get along the way.) I thought about this, but the dial foot screw doesn't seem to be wide enough to get the thing out if I could advance it into the hole.  I suppose that I could try and take it out in pieces (advance it as far as it will go, get in there with some sort of saw, take a piece off, walk it forward again, take another piece, etc) but that seems like alot of risk to the main plate. I need to examine the other screw to ensure it doesn't have a shoulder or something that would prevent me from doing something like that.  However, all that said, I've been unable to get the thing to move at all. In general, this whole piece feels like someone had it before me, did a bad job of working on it and ultimately just bunged it all back together in a haphazard way and passed it on to be someone else's problem.
