When I pulled this little omega 484 down I noticed that the escape wheel was turning under duress so I thought I would show how I polish these tiny pivots on the escape wheel and pallet folk before I ultrasonically clean them. It gets a nice shine, I can do my hair in the reflection. Using a very fine pin polisher

What abrasives do you use?  Any compound?

Would this taper the edges of pivot head?  

 

 

No it doesn't taper the edges, in fact you can also polish the pinion shoulders at the same time. No abrasives used as such. Just a 3mm very fine pin polisher which I push over the pivot and gently rotate until shiny. I also do the balance wheel pivots. I do this before the ultrasonic wash it's a sure way of getting the pivots in optimal cleanliness. Hope this helps

Hi Is it possible to have a little more detail of the polisher you use, looks interesting.           Cheers

https://www.eternaltools.com/mini-rubber-silicone-pin-polishers watchweasol hi these are a must have , I only use the green ones as they are great for pivot polishing and remove no material  and when you combine this polishing with the burnishing of the pallet fork on vintage watches you can bring your amplitude up considerably , on any watch .Hope this helps

I've been curious about these pin polishers for quite a while, so I ordered the following from CousinsUK:

In hindsight, I regret not ordering the two-millimetre versions instead as the polishers tend to hit the fingers/tweezers when rotated.

Yes, indeed, but it depends on the hardness and grit. The medium grit and medium hardness polisher will quickly taper the pivot so stay away from it. It's very aggressive.

I would say all you need is the extra fine grit and soft polisher. As far as I can tell it doesn't remove any material, except for perhaps a few microns. Of course, it also depends on how long you keep polishing.

Although I made no extensive tests with the fine grit and soft polisher I'd stay away from that too.

Just to make sure. Do not think that these polishers can be used to burnish/repair the pivot. A Jacot tool is required for that. However, for cleaning they are well suited.

Something else to add to my cousin's order list , i had considered them previously but your suggestion of size and limited grit usage has saved me a few quid . Thanks watchie. I wonder if use in a rotary cable would be overkill, the one i have is very small and can be reduced to a low rpm.

Although I don't have a rotary cable it sounds like overkill to me!

I think some tasks are more suited for the sensitive touche of hand work.  Power tools often help us make bad parts more efficiently.

I can't see how polishing doesn't remove at least some material,  Even as VWatchie says, it may be down in the microns.

These look very interesting.  Thanks for the heads up, I will definitely be ordering some.

I have just one question; Will these help in correcting mistakes within my correspondence?

I'm afraid not! 😄

Oh, and I do agree! Power tools should be used with great care in watch repair. I now have an excellent Proxxon rotary tool (fantastic!) but I limit its use to polishing watch cases. Power tools can make things go very wrong very fast.

    • Hi, this is the first place I found when looking for advice so I hope someone could advise me.  Im completely new to touching watches but I’ve always wondered how they work.  I’ve bought a cheap movement, an ETA replica to take apart and rebuild.  Im thinking I’ll need some screwdrivers, tweezers, movement holder and a loop? My goal is just to have a go first and see if I enjoy it enough before buying more tools.  Do I buy cheap tools for now and get better quality tools later if I enjoy it like I think I will? or will the cheap tools be a pain and take some of the fun out of it?  With quality tools being relatively expensive I’m unsure what to buy.    Any advice would be greatly appreciated!
    • Yeah I have seen 44-56 documented for Elgin 18 size elsewhere. I have the style of gauge that's like a set of feeler gauges and I never noticed before today it is faintly stamped "Elgin". Pictured is the way I have been measuring. I am going to go to a larger jewel than the 42 that had been in there. I recently won an auction on a big set of Fitrite jewels all in the little bottles, to discover that the what's actually in the bottles bears no relation to the chart of sizes printed on the box. In most cases it seems to be all mixed so in fact I have about 24 little bottles and thousands of assorted jewels of all diameters and lengths, which is better than nothing. But since I don't have a micrometer with a table, measuring for the exact diameter will be a big job. Instead I will test a lot of them in the fork slot the same way I measure with the gauge. But this is still the next thing. I have to get the escapement to unlock first.
    • 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
