Stuck with taking a Landeron 48 out of the case

Hi all,

So, I took a little break in destroying my practice movements and wanted to improve the look of my two chronographs (Fidelius branded Landeron 248 and Orator branded Landeron 48) which were quite dirty.

The Landeron 248 has progressed really well. I was able to open the case, remove the movement and dial and separate the glass. I then polished the scraped up acrylic glass with Autosol Metal Polish (yes it works!) and was able to insert it back into the now cleaned gold plated case (I cleaned the case with a Mr Clean wet magic eraser sponge, works well too). I carefully cleaned the dial with Rodico first , but the result was not that much different. So I gave it a try with mineral oil, which I then wiped off with a clean tissue followed by again a Rodico treatment. That seemed to improve the look nicely without damaging anything. I have unfortunately not taken photos, so I will provide these later.

The issue I am now facing with the Landeron 248 is that when putting back on the chronograph minute hand, I can not seem to get it right in how tight I put it on. At first I put it on as tight as it would go with a guided hand fitting tool (still a light press of course) but that was too tight and made the movement stop when the chronograph was about to hit the minute mark. I then retried several times by putting it on as lightly as it would go without turning around freely or falling off, but I either press it on too hard (and make movement stop) or too light (as at some point it will start to swing freely or fall of). Is there any trick to it?

On the Landeron 48, I got stuck way earlier, as I have been utterly unable to remove the movement from the case! I proceeded as with the Landeron 248, meaning that I unscrewed the back, removed the two movement holding screws and removed the stem. At that point, I was able to remove the 248 as it was then only held in my a metal spacer. The 48 hwoever doe snot budge and it looks like the movement is slightly larger than the back case opening. I can however not see how I would remove any part of the back to enlarge the opening (I thought maybe the bezel that the case back is screwed on could also be screwed out somehow, but it does not seem like it). So I thought that maybe you had to remove it through the glass and was able to remove the front glass with the relevant glass tool. But the movement still does not come out and does not budge at all. So I am completely clueless now. Any suggestions are welcome. I attach some pictures of the 48 as it is now. Sorry if the quality is not the best.

Olivier, the movement comes out through the front, but first you must remove the bezel.

To do this start be carefully pressing a single sided razor blade into the joint between the bezel and body, sometimes there is a very shallow notch to allow a blade easier access.  Once you have lifted it slightly with a razor blade, use a Stanley blade, that is slightly thicker, to lift it a bit further.  Once that is done, finish off with a case knife to prise the bezel off completely.

By doing it is stages, there is less chance of damaging the mating surfaces of the case and bezel.

      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.

      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.

      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.
