Having just finished Mark Lovick's excellent "Maintenance Servicing" course, I'm now reassembling a Poljot 2614.2H movement. Unlike the the Unitas 6498 in the course, this movement has a friction point which I don't know how to releate to. It's certainly not easy to formulate a correct question, so I'll back it up with a couple of pictures.

Should any oil be applied to the friction point between the jewel (on the inner/intermediate bridge) and the fourth wheel pinion, and if so what kind of oil?

A spot of 9010 just under the pinion and also on the wider portion of the pivot.

Yes... D5 - as always, not too much. bbf9c04b3cb73985860782b2f3673fed.jpg

      Hello again.
      I was checking the performance of my Strela chronograph (Poljot 3133) and found an interesting anomaly. By looking at the timing graph, I would say that aside from the watch needing some adjustment, one of the two swings seem to be inconsistent. Am I right in stating that?
      I was pretty confident that I will find some obvious problem with the impulse pin, pallet jewel, or escapement. But taking these parts out of the movement and reviewing them under the microscope did not reveal any obvious problem. Nothing seems loose, damaged or bent. I then cleaned the parts and put them back in the movement and as expected got the same anomaly on the graph.
      I am very much in the mood to disassemble, clean and oil the whole mechanism but before I go there, I thought it may be a good idea to check with the forum on what is likely causing this behavior. I am attaching some photographs of the parts but they were made with my phone pointed through the eyepiece of the microscope and may not contain enough details.
      Guess I should also say that this is the first time I will be fully disassembling a chronograph.

      I’d be surprised, but very happy, if anyone has the knowledge to help me out with the following.   I’ve bought a Russian watch having a Poljot 2614.2H movement (Cornavin Dolphin) on eBay  which I’m now servicing. My problem is that I need a new mainspring for it (or barrel complete) but I’m unable to find anyone who can supply it.   I found some other Poljot mainsprings on eBay and CousinsUK.com, but non for the 2614.2H. For example, on eBay I’ve found a mainspring for a 2609/2614B, and on CousinsUK.com I’ve found a barrel complete for the 2609. However, I have no idea whether those would be compatible with the 2614.2H or not?!   Here are the measurements of the mainspring I’m looking for: Height: 1.15mm
      Thickness: 0.12mm
      Length: 330mm (approx.)
      Inner Barrel Diameter: 10.48mm   I should also mention that it needs a “DB = Special Bridle” as specified by the Generale Ressorts catalogue on CousinsUK.com, which I’ve also browsed but with no luck. Below are some pictures of the barrel and mainspring I’m looking for.

      I have been servicing a Poljot 2612 alarm movement - everything stripped, cleaned and 99% reassembled - however I an really struggling with getting the balance back in.  I've now spent 3 separate sessions just trying to get the balance in - but still no success.   Very frustrating.
      I notice that there are a few references in these forums of people having serviced similar 2612 movements - so I'm wondering whether there is any advice on the best / most successful way to re-install the balance?
      Any help/advice would be greatly appreciated.
      Many thanks,

    • I’m going to bed now. This looks quite easy to sort for you. I’ll let you know how to go about it tomorrow.
    • Here are a few pictures as requested. Sorry for the orientation. I will rotate them as soon as I learn how.
    • I have a copy of that book and read it cover to cover but very useful for browsing topics if you are working on a particular repair, I guess Lauries book covers most if not all of it
    • I am well pleased with mine came in handy tonight whilst rebuilding a regula 25 cuckoo clock for checking pivots. I have a balance spring to sort out soon so again will be in use a useful tool when you consider a bergeon hand gauge is nearly £40 .
    • It would depend upon how the strap attaches to the case. Based on what I can see, my hope would be that you can remove the caseback and then slide the band off with some kind of tongue and groove fitment. If that's the case, my inclination would be to 3D model a piece that would slide in as an adapter and can accept standard bands with springbars and then 3D print it. Once you have a design that works, send your design off to one of the places that can 3D print in metal to have them create a more attractive and durable long-term piece. A couple that does Youtube videos on making stuff called "Evan and Katlyn"  went through this process in a series of videos a few months ago for making a custom folding knife. They have lots of guidance about the process in those videos.

      Good luck!
