Hello All;

I'm working on a Soviet Raketa 2623.H and it starts to look like that one of the very little escape-wheel anti-shock springs is winning the battle.

The spring on one side is out, bit this one is putting up a stiff fight. I can squeeze both tips, but as soon as I try to lift them, the tweezers snap off. I dressed the tweezers tips, tried different tweezers etc etc, but so far no success.

Two questions;

1) Has somebody some tips or tricks to safely remove this little bugger ?

2) What to do if I just can't get it out? With no spare on hand, I don't want to brake the little spring either.

How best to "clean" it when no fancy cleaning-machine is on hand. Its been in the lighter fluid for over 24hrs, but obviously I like to get the cleaning fluid out before oiling with an incabloc needle oiler. Would forcing air through it (on the "open side" with a hand blower) be enough the "squeeze" the fluid from underneath the cap-stone?

Suggestions / ideas are very welcome 😉

That looks like a tricky bugger. Curious that the bottom prong looks longer than the top one. I don't have any experience with these, but if it were me I'd try to get the two prongs free of the slot, then try to push the whole spring to the right of your picture.

Either that or prize up the top spring with a fine tweezer point and work it around to the left. I think you'd risk bending it this way, though.

In either case, I'd have plastic or Rodico over it. That looks like a prime candidate for the Swiss Space Program.

Probably not. I'd warm up the mainplate to evaporate it.

Good news to report 😃

ManSkirtBrew was in the right direction. Under the microscope I used, while preventing the spring from rotating and with the spring in the same orientation as on the picture, a sewing needle-tip pushing from the right to the left, to lift the shorter prong. Because being under a microscope, I used Dumont N˚7 tweezers to push the shorter prong over the needle to the outside from left to the right. Basically, the sewing needle acted like a ramp upwards for the shorter prong. Slowly working the spring out of its recess.

The shorter prong was slightly bend upwards, but after cleaning the cap-stone and the pivot-jewel, the spring was installed "upside down".

Another interesting question would be, why such an "anti-shock" system for an escape-wheel 🤔 ??

If I well remember, my Rolex 3135 had the same, but here we are not talking Rolex .......... or do we?

Anyhow, thanks for you help, another lesson learned 🙂

This has nothing to do with antishock. Just cap jevel fixed in place by the spring. In Rolex too.

I've come across these in a few different Russian calibers. Used acupuncture needles in the past but the steel tend to be a bit aggressive for these little springs, they are quite weak as might be evident on yours, i dont remember the locating tabs being of different lengths. I now use a toothpick with a condom on the end ( dont ask !!  Well actually maybe you should ) and a titanium probe which is more forgiving than steel. Dont release one tab and then try to draw the spring out, it will either ping on you or snap if you are unlucky. I find it best to release both tabs,  and use the condom pick to hold it in position while you do this.

See, the pivot is like a pivot of balance staf, the shoulder is rounded. The tip must rest on the cap stone, so if the capstone is removed, big axial free play will be there and even the down side pivot may go out of the hole. Why? Ask the manufacturer... For prestige may be. But on dial side no cap stone and normal cylindrical pivot in normal jewel

Like the endpieces that were marked up on the fhf that i did.  🤔 dont know why, but i know which i prefer removing and fitting.

This movement has capstones on either side.

Both springs had one shorter tab. The movement was untouched, therefor the little retainer springs were in original shape.

Bumps up the jewel count.

There is no mention of the number of jewels on the dial nor on the movement. As I once read, in the Soviet period, from a commercial point of view (unlike in the west), the amount of jewels wasn't considered such an important sales point. I don't think that they added these jewels to boost sales. Prestige is a possibility ... 🤔

👍you may well be right, its just something i dont remember seeing ,  it is possible that they were poorly manufactured. The Russian quality wasn't great at that time, there is a video somewhere in the forum archives of the Raketa factory from years ago, it was wow nonexistent health and safety for starters. I have quite a few of the train bridges kicking around, i will dig them out as soon as I've had breakie and come back to you.

Had the same problem not too long ago! Very nice watch BTW

Wish I would have known ..... 😬

In the end, I solved the problem in same way as you did and clearly, the shorter leg of the spring is by design. If I would have known your article, perhaps I would have had some more hair left on my head 😂

And that's another thing, most articles just get lost in the dust-bin of data-bits ......

Absolutely right Endeavor, I've just pulled a couple out, the legs are indeed different lengths. I either didn't notice at the time or more likely just didn't remember.

The post I linked to was from when I serviced a Raketa 2609.HA, but when I later serviced a 2623.H (same as yours) I believe I found it easier to pray on the long leg. I'm not perfectly sure I remember it correctly but I thought I'd mention it.

While we're on the topic, I intended to create a service walkthrough for the Raketa 2609.HA, but never followed through. Not that I think you need it @Endeavor but for what it's worth here are links to my raw images for the intended walkthrough.

When I later serviced the 2623.H, the only noticeable difference I found was the cover plate over the dial train/motion works.

BTW, I had a very tricky problem when I serviced the 2609.HA. After the service the train wheels were binding and it took a lot to figure it out.

    • Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with. I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements.  Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!
    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
