Hi gang,

So, I am new to all of this, and I want to learn about mechanical movements. While I am waiting on my test watches to arrive, I figured I would take a look at one of my personal quartz watches that is messed up. It is a Citizen watch which had water damage and needed a new movement and seals. I took the watch apart and ran into a problem. The plungers, rather than being held in by a metal e or c clip, are held in by little plastic sleeve / clips. Unfortunately these clips are all broken and need to be replaced. I have scoured the Internet and have not been able to find replacements. 

I can't take a picture of something this small, so I drew the attached picture. Basically, the waist portion of the plunger where the clip goes is 1mm long by .6mm shaft diameter. I had considered using metal e or c clips instead, but I think I would need to stack several of them to achieve the 1mm width. 

Does anyone know where I can purchase these plastic clips or if not do you have any thoughts on using stacked metal ones instead? Given that the shaft diameter is .6mm, do you know what size e-clip would fit that? They seem to be sized by outside diameter, which doesn't really help me.

Thanks so much

That is a new one for me. The quartz movements I have worked with are secured with one of these :

You can purchase a selection from material houses such as Cousins.

Don't feel guilty about fixing quartz watches - I do it all the time!

The problem you face is that parts for more everyday watches are rarely available because most owners replace the watch rather than have it repaired.

I had a similar problem recently with a quartz Seiko chrono that was missing a pusher. I managed to find a scrap identical watch on eBay that was missing several things but had two good pushers. The finished repair had the best parts from both watches (the donor had a perfect crystal).

If you can't find an identical match, you may find that similar Citizens of the same era will have useable parts. It's worth considering a joblot of scrap watches as a source of hard to find parts.

Good luck

You can try getting the smallest of these:

Get a pin vice and very fine saw blades. Cut the tube to length and then longitudinally.

Have this but see now that they could be a little bit to large? The diameter is 0,9 instead of 0,6. I recently worked on a Citizen 8950 lcd watch that had those small c-clips. 

The other is a Pulsar watch that have some kind if clips?

Hey thanks everyone. I guess it would be like trying to find replacement parts for a modern toaster. Their probably aren't any because you just throw the thing away.

The clips on my watch look very similar to the ones in Rogart's second picture. I think JDM's idea of fabricating one out of a tube would be a pretty cool idea, though possibly above my current skill level. I may play around with that though in my spare time. I think that to get it in service for now I will just try to put some metal e-clips on there and see what happens.

Thanks

It's actually quite easy. If you can remove a C-clip without loosing it and placing it back, you can adapt a generic tube to become a pusher "sleeve".

@jdm Maybe I'll give it a go then. What type of saw would you recommend for making the cuts, in particular the lengthwise cut, as it seems that the kerf if the blade would need to be about .4mm (just guessing)? Although I guess that if it were too big I might just be able to crimp the sleeve down a little bit. Also, would you say that it is easier to cut to length and then cut the slit or vice verse?

Thanks a bunch.

I'm, sorry. You actually already answered some of my questions. In your original post you said cut to length and then longitudinally. Also, you mentioned a very fine saw blade. Is there some type of saw that watchmakers or jewelers use for this type of thing? I come from a wood working background, so I ten to think of fret saws or something similar, but I wasn't sure what type of tool you would really use for this.

Thanks.

Just thinking here? Maybe not working? But could one use the  plastic tube? Like the one on WD40 cans? You now the red one? And cutting small pieces of that and putting over the pushers? But maybe the hole is to large?

Yes, piercing saw blades. These are very economical and always useful for many kinds of repair. Cut to length and then slit. I do the same to replace the collars which are easily lost when resizing bracelets.

@jdm I purchased the tube, saw, and blades to try and make the sleeves like you talked about. Cutting them to length is easy enough. Cutting the slot along the length has been a bit more challenging. I've tried holding the tube with electronics needle nose pliers, which didn't work at all. I tried pushing it onto a sharpened piece of of peg wood and and cutting it. This actually worked (sometimes) but I also tend to lose the tube when it falls off. I have been most successful by feeding the tube onto the saw blade and cutting it from the inside out. 

In the end, I think my lengthwise cut needs to be wider, as I have had trouble getting the sleeve snapped onto the pusher shaft.

I really appreciate the idea, I just need to get better with my execution.

You are exactly right, cutting a tube in length is not that easy.

I place it on a vice and pray that it helds. Cutting from inside seem a great idea. Let us know how you do.

    • 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
    • At work, I'm on MS Edge, not through chose, on my phone, chrome, no issues with either.
