Missing jewel after cleaning

Hey guys,

This is a frustrating one.  I was reassembling this elgin 12s pw and discovered that the burnished-in jewel for the bottom plate palate fork was missing.  This, after cleaning the movement in the watch cleaning machine and again in the US (because it got dirty again) and after buying a replacement dial and balance hole jewel.  It must have just shattered as i can't find it anywhere and, of course, it was burnished in.  I now have two PWs that need burnished in jewels.  I could probably justify now getting the proper tools to fix them, but i'm going to set it aside to better develop my basic skills before tackling these repairs.  I don't know if i was negligent in handling the cleaning or it was just old and bound to happen.  Anyways, another lesson learned.  🙂 Arron.

was missing

Depending upon the age of the watch a lot of the stones may be natural. They tend to have all sorts of in trouble flaws anyway and some places where people are enthusiastic when assembling they can break the stone. You probably have grit in the bottom of the cleaning machine were of course it came out in pieces.

burnished in jewels

Burnished in jewels can be an issue to replace. At one time there was a assortment of burnished in jewels. Pick the right one if you're lucky and burnished a new one in but you do need the tools to open up the setting and close setting again. Or you can modify a modern jewel to the shape suitable the burnished in. Or just ream it out and put a modern jewel in but that will have issues for other reasons like sometimes end up having to open up quite a bit to get a modern jewel in. Plus of course modern jewels are distinctive red color versus the pale stones the past which may have been garnets or something else not necessarily sapphire.

i had a feeling it wasn't going to be easy, but maybe by the time i get to doing it, it won't seem quite so daunting. 

It might not actually really be that bad. The problem becomes we want to do the repair now versus when the watch was being made. That's really the biggest challenge is trying to find stuff to fix a vintage watch.

      First Project Already A Bit "Sideways"

      By DDean · Posted

      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.

      attached is the tech /parts sheet. .   Can one ask how come it’s full of water. After being told that the waterproofing was not guaranteed.  Problem being electronics don’t mix especially withe the power source being attached.  You may be lucky but I should look out for a replacement movement or working donor to rob the movement from.

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

      By JeremyLaurenson · Posted

      I thought this may be "right" forum to post this. After 7 months out in Switzerland I got my Navitimer back from Breitling. I had sent it off since its 20 years old to have a complete overhaul done... Nothing major wrong, but I did notice this seconds sundial skipping thingy.... $1300 later and 7 months later, I notice the 'skips' are still here unless the chronometer is engaged. I would think this is likely the hand binding up and maybe clearance with the dial, but at any rate Im interested as to whether this is something I should be returning the watch to Breitling for and insisting on being fixed. See below - 1 minute or so of regular running and then 1 minute with the chronograph engaged.

      Unknown mechanism

      By Giogrlj · Posted

      A friend of mine just gave me an old pocket watch. The case is in very bad condition but the movement itself seems to be in a quite good shape. I can't identify which movement is this, since I have to find a missing winding stem. I attach few photos in a case somebody would be able to give some hints.  Thank's folks
