I have been given a 2824 where the weight can turn one direction only. I found that on the reversing wheel closer to the reduction wheel, that is the one with two jewels, the smaller gear can only turn counter-clockwise when placed with the round holes and jewels side up. That is the opposite of the way it should be.

I know that the previous person that has been to the watch must have had the same problem, and gave up on the automatic completely, as the reduction wheel is missing, as weel one screw for the automatic bridge, and the caseback gasket. Incidentally, as this comes from a small town I have a definite suspicion about who may have done that, having seem his butchering before

Now, I can easily order spares and even have some working mov.ts to borrow from, my question is how that can happen?

I have never taken apart a reversing wheel and wonder if it's in teory possible to install the one-way fingers upside down? Altough, there are no evident signs of having been opened.

If you live long enough you will find there are people who can make things fit even upside down.

I am one for sure! Cheers mate.

I have taken the problematic reversing wheel aside and I am still puzzled.

I did not mention before, but the wheel in question has two jewels on the smaller gear, but not the pinion to mesh the reduction wheel.

So one could think that an auxiliary reversing wheel had been fitted by mistake, but on the 2824 only the wheel with the pinion should have jewels, maybe because is the one subject to more force.

Anyway isn't really possible to asembly the inners of the other way around AND have it working. The fingers have a pivot that must enter and be visible in the holes of the smaller gear. It counts up to 8 parts and putting it back together is a bit of a delicate job.

    • it would be nice to have the exact model of the watch the or a picture so we can see exactly what you're talking about. this is because the definition of Swiss watch could be a variety of things and it be helpful if we could see exactly the watch your dealing with then in professional watch repair at least some professionals they do pre-cleaned watches. In other words the hands and dial come off and the entire movement assembled goes through a cleaning machine sometimes I think a shorter bath perhaps so everything is nice and clean for disassembly makes it easier to look for problems. Then other professionals don't like pre-cleaning because it basically obliterates the scene of the crime. Especially when dealing with vintage watches where you're looking for metal filings and problems that may visually go away with cleaning. Then usually super sticky lubrication isn't really a problem for disassembly and typically shouldn't be a problem on a pallet fork bridge because there shouldn't be any lubrication on the bridge at all as you typically do not oil the pallet fork pivots.  
    • A few things you should find out before you can mske a decision of what to do. As Richard said, what is the crown and all of the crown components made of . Then also the stem .  The crown looks to have a steel washer that retains a gasket. So be careful with what chemicals you use to dissolve any stem adhesives or the use of heat. You might swell or melt the gasket unless you are prepared to change that also . The steel washer maybe reactive to alum. Something I've just used to dissolve a broken screw from a plate. First drilled out the centre of the screw with a 0.5mm carbide . Dipped only the section that held the broken screw in Rustins rust remover. This is 40 % phosphoric acid. 3 days and the screw remains were completely dissolved, no trace of steel in the brass threads. A black puddle left in the solution.
    • I suppose this will add to the confusion I have a roller jewel assortment. It lists out American pocket watches for Elgin 18 size and even 16 size it's a 50. But not all the various companies used 50-50 does seem to be common one company had a 51 and the smallest is 43. American parts are always interesting? Francis Elgin for mainsprings will tell you the thickness of the spring other companies will not even though the spring for the same number could come in a variety of thicknesses. But if we actually had the model number of your watch we would find it probably makes a reference that the roller jewel came in different dimensions. So overlook the parts book we find that? So it appears to be 18 and 16 size would be the same sort of the arson different catalog numbers and as I said we don't have your Mongol know which Log number were supposed to be using. Variety of materials garnered her sapphire single or double but zero mention about diameters. Then in a section of rollers in this case rollers with jewels we do get this down in the notes section Roller specifications but of course zero reference to the jewel size. I was really hoping the roller jewel assortment would give us sizes it doesn't really. But it does show a picture of how one particular roller jewel gauge is used  
    • Seems to still do it through my mobile data, I use an android phone almost exclusively, but I'll double check it. Thanks mark Strange, I'll try my laptop that utilities edge. I've been on site half hour since I got home, it hasn't done it yet. Thanks John
