Does anybody have experience of the Luch 2209 calibre. Its a beautiful thin watch, bought it on Ebay for a few quid but it ha an uneven tick and stops regularly. Any ideas suggestions offers of help greatly appreciated.  I love Russian watches. Recently replaced a click spring on a Slava/Sekonda  2414 and it keeps great time now.

 Move the stud arm to bring the impulse jewel in beat. 

Top close up of balance, pallets please.

A drop of lighter fluid on arbors/ pivots and pallets will provide temporary relief from old oil.

"Uneven tick, stops regularly."

As suggested sounds like the balance.

Demagnitize first, then clean and inspect hairspring, clean and inspect pivots and so forth.

Check the fork pivots, jewels/pins.

Check the impulse jewel lies in the correct place when at rest, in case hairspring has been deformed in some subtle way.

If all of that looks fine, then let down the mainspring, remove the balance and fork, and ensure the power train runs freely.

It might also be worth finding a similar movement on ebay and swap the balance and fork, etc till you find the offending part.

You can buy buckets of these movements from eastern Europe.I have yet to work on a Luch 2209, but I  can tell you other Russian makes can be made to run quite nicely . Provided they have not been dredged up from the bottom of the Black Sea.If you need parts try looking on ETSY. There are numerous vendors in Latvia and Ukraine that have bare used movements.

      Thanks Mark I have uBlock Origin Lite add-on for my Windows Chrome browser, so I've never seen a single ad on this site ! It also removes all adds from Youtube - I couldn't bear to watch it without uBlock

      You're probably not going to see a dramatic change but you should probably figure out what the lift angle is as it probably is not 52°

      In tandem with my last post regarding the removal of Google Adsense on this website - I have also decided to fully self fund this site as a gift to the watch repair community of which I’ve been a member of, and have benefited from since being extremely lucky to gain an apprenticeship back in the late 80s.    Well, that means that I have also closed down my Patreon account - or, to be clear, stopped all future transactions on my Patreon account and this is with immediate and permanent effect.    not to mention, but I will, I really really do appreciate the contribution all my patreon and PayPal supporters have provided over the years, you guys have been absolutely awesome and helped to keep this forum alive and available for those who might not be able to afford the payments.    again, from the bottom of my heart thank you.

      My pleasure. I would rather pay more than have those annoying ads ruin this site. They were a terrible idea and something I never even saw much, but I was on my iPad yesterday testing a security update for the forum software and it was impossible. I decided then - they had to go!!! Also, co-incided with this, for those who are paying for pattern in order to help fund this site - I’ve just disabled patreon. Future monthly payments will not be taken.  PayPal is a little more complicated. I will try to work out how to cancel the few subscriptions but if you are a PayPal donator then please feel free to cancel the monthly sub.  I will, however thank you all from the bottom of my heart for helping to contribute to this site financially - it means a lot. But going forward, I’m funding it personally from my pocket and that’s the end of it 😄
