New Movements For Practicing On, Very Cheap.

Recommended Posts

I took one of the movements apart last night and have it soaking in Naphtha.  Tonight I'll run it through the ultrasonic a few times and then inspect.  I need to get back to fixing the hairspring on the 6498 that I'm using for the TimeZone course but thought I would try to get one of these working to get me back into the swing of things since it's been a few weeks.

Looks like these movements just need some intense cleaning.  I was able to get it running smoothly if the movement was face up which was odd until I realized I accidentally removed the shock jewel on the other side which I assume caused too much friction when flipped over.  I put everything in a plastic bag and will try my first attempt at cleaning/replacing these jewels.

Soaking it overnight in Naphtha and 4 cycles through the ultrasonic did the trick.  There was still some caked on oil that I got off easily with some pegwood.  I bid on a Zenith cleaner on eBay yesterday since the seller was pretty close and shipping was reasonable.  I assumed it would go for at least $75 based on previous sold listings but I ended up winning it for $45 + $18 shipping so cleaning should be easier in the future.

Yes they are small. It's a lot easier with the tool i made. It's really just a tube with the correct ID and OD to press on the spring near the outside edge. You press on it lightly and rotate to preload the spring a bit and get the tabs engaged. Maybe not the textbook way, but it works and doesn't damage anything if you're careful.

I'll try to post some photos tonight.

Grizzly. Not a watchmakers lathe. It's chinese made but I've done a lot with it over the years. You just have to know it's limitations. I would like to get a big old US made lathe like but i dont really gave the room to spare. I can do everything I need to worth this one, at least most of the time.

What is the proper way? Once you learn it, please let me know if you don't mind. I tried inserting one of the tabs into the groove, then working the next one in and so on, but each time I would rotate it to engage the next tab, the previously inserted tab would pop free. It was maddening, which is why I made that tool. Maybe some of the more experienced folks will chime in here and enlighten me. I'm sure there's another way, but this works for me. I would like to know the proper technique, I am mostly into 60s and 70s Seiko models right now, and they use a similar arrangement on some of the jewels. I did read somewhere that there is a similar tool available (KIF maybe?)

I found this by typing "kif tool" into google. The section on the right shows assembly procedure, they use a piece of pegwood shaped in a way similar to the tool which I made. It's very possible that I saw this before somewhere and that's where I got the idea. Maybe it was lurking around in my subconscious or something, waiting for the right time to become important. Anyway, have a look. I think if the manufacturer of the jewel setting recommends it, then it's ok to use. I should have made mine from pegwood though, rather than aluminum.

Thanks for the info.  I guess using a tool similar to yours is the proper way.  After looking back at what I did during cleaning I think I already made something similar with pegwood albeit with less precision.  I used a knife and made a point and started to clean some of the jewels and areas with caked on oil and I think that is probably when I accidentally removed that spring.  I'll have to try putting it back in with the same piece of pegwood.

    • At the lowest magnification, I can just get all of a normal wristwatch size movement in field. For some things it's too much magnification, but the nice thing about the eyepieces is they only take seconds to swap in and out. I'm genuinely surprised I've never read about anyone else doing it, to be honest.
    • The K&D (Levin made the same style too, probably others as well) are a clever design and work well when you get used to them. The only issue is if you wind the spring so that the tongue goes in, there's a really good chance it slips futher and then comes out  the next slot, usually breaking off. Best to size it so you can fit it in the barrel with the tongue sticking out.
    • I guess that's me... I work with various pumps, motors, sensors, computers, PCBs, and lots of code and chemistry. Couldn't tell you much about life with a mechatronics degree, as I've never heard the term before. My degree is in Entrepreneurship, and I bootstrapped all the technical stuff (my superpower). On the face of it, it sounds like mechatronics is the better way to go between the two, but it seems hard to imagine a mech E degree without a lot of code and electronics these days...   Whatever happened with his CS project, btw?
    • Totally Andy's brilliant idea. I just started the thread.  For what my opinion is worth, the number should be quite low. That's the point of it. It's as much about the hunt as the act of servicing/repairing the watches. I don't have too much of an opinion on currency, but £ has a slight edge since that's what it started with. This is a global forum, so the majority of people will be converting values no matter what. I don't know if there are any currency traders here, but if there's any currency that's especially stable or some other attribute that would benefit the game, that could be amusing. Maybe one that's super volatile? Qualification is heavily influenced by what wacky things some currency is doing on a given day (though usually that means shrinkage). We could go for something super obscure like the Chilean Peso or something just for giggles (though it might make conversion difficult). A lot of currencies are indexed to the US$, which would ease some of the conversion friction for some people. Just spitballing. My vote in the poll would be for £ inflation adjusted to £4.04 ca. 2020. I'm ticking those boxes, but I'm not sure about the 6.99. Is that £, or another currency? Source?
