Do you think this was put there during manufacture or repair?

Should I put it back in or try it without it first?

This is common in Russian watches and should be put back in place otherwise the balance will not have enough end shake and you will encounter poor balance amplitude, they are an absolute pain to put back sometimes they are hard to keep in place.

Was this under the balance cock? If it was I have seen something like this before on an american watch . I believe it was to keep the balance stem up just a bit. I know the watch woulden't work without it. I doubt it was factory installed

It's the Sekonda Poljot 2614.2h.

All cleaned and I'm starting the re-assembly and I noticed the shims...

I've seen these in Russian watches.  I put the balance on and make a few turns on the screws and then slip the shim in.

Without the shim the balance will be too tight.

I can wholeheartedly recommend the Vostok 2409/2414 movements and the Poljot 2614.2H movement to any beginning watch repairer.

Oh yes, a shim is sometimes used, but it works and I consider that a lot more serious than making a "bump" in the main plate as the Chinese do.

I have serviced a few Sekonda watches and found them OK to service with good results.  I have had no experience with Poljot.

The SEKONDA uses a Poljot 2614.2H.

Getting back to the original question I have found shims in a few vintage watches and in the occasional pocket watch. I think some Russian watches have them fitted as standard. For others it is where a new staff has been fitted and it is a bit tight. The correct method is to hone the staff to the correct length but some revert to the shim method to save time

   do the Russ factory or any country put  a shim under the bridge?  vin

I can assure you these shims are indeed part of the movement. Back in the 70’s and 80’s all the Russian movements of that period had them.  They were machined to size and shape to fit under the balance cock.

Yes I have the same part only my problem is that my balance is loose and broken from the cock. I have three new balances but can't get it attached. Help

    • 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.
    • I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
    • No, I now realise it’s broken😥 ive looked for one online, but v. Expensive! im going to service as is, in the hope that  one turns up. Thank  you.
