Russian movement hairspring removal


Recommended Posts

I have been working on a old Russian watch movement I got off of ebay. Don't know the manufacturer right at the moment, but anyway it was rusty and very dirty.

Was working on cleaning and reassembly when I ran into an issue, the hairspring stud. Or how it was mounted, not with a screw but the mount was spring loaded.

I was able to push the hairspring stud out of the mount, but failed miserably trying to but it back in and broke the hairspring stud holder.

My question, is there a tool or method to replace these hairsprings mounted without a screw, something to open up the mount so the stud can be inserted? My screwdriver attempt did not work.

A photo would be nice.

If it is the type I'm thinking about then you could try a screwdrv (which I believe you already tryed) or a right size screw (a bridge or a case one) - you screw it an the stud holder just lets go of the stud.

It is similar to the one in the link you sent, Thanks Mata!

Did not think about trying a screw, the screws that were holding the movement seem like they might work.

The holder is now broken so a picture might not be of much help. Since this is a junk movement anyway, I might try to use a small amount of epoxy to hold the stud to the holder.

    • Interesting, but not very accurate, unfortunately. Using the word "Radiation" without specifying the specific type of radiation [what is being radiated] is one of the commonest mistakes - and most confusing to non-technical people.  Also, I believe the commonest lume in general use nowadays is just a phosphor compound that is "charged" be exposure to light? I've never personally see a watch with tritium lume, and it's not something I would particularly want as the decay is quite rapid with a half life around 12.5 years. Tritium is also of course radioactive, emitting beta particles, and it can possibly cause cancer if ingested!   Re. geiger counters, it's also important to note that many on internet sites are fakes that detect RF rather than, or as well as, ionising radiation. Or just low quality that likely only detect gamma, or gamma and alpha. Only high quality mica window GM tubes will detect beta; all the cheap geiger counters I can see on on ebay at present that show the tubes, use glass or quartz - despite claiming to detect beta   
    • Some things that we think of as relatively new or modern have been  around for a very long time. Alloy mainsprings, balance wheels and hairsprings and epilame for example were developed over 80 years ago. I use clear nail varnish for glueing crowns on, as well using it when making fibre bristle oilers and tweeking tools, its easy to apply if you get a move on after taking it out of the bottle and sets nice and hard.
    • Hi you will probably find there are a few citizen movements the same or close due to manufacturing processes.
    • Hello, How do I open a screw back cover on a hidden lug watch? It is perfectly round and rotates in the watch holder.   Thanks!
