Hairspring Frustration


Pip

Recommended Posts

No, that's not the reason. Seiko hairsprings are extremely easy to get distorted, and equally difficult to correct. read below:
 
 
 
Hmm, I understood that the distorted hairspring from the beginning of the thread was all good a few mins agao then all bunched together again still out of the watch.

The two gaps marked with red should be around the same. Since it is bent somewhere at the yellow marking the whole spring is pushed towards the green direction. 

 

Did you demagnetized the movement and the balance and cock assembly separated?

Totally possible when you treat a Seiko HS like it was a sturdy one, with dangling, etc.
You need to work on some to see what I mean.

I've moved some cleaning postings to the correct thread.

Both separately and together. Several times.

Thanks for all the support guys. I tried to follow as much advice as I had the competence to and cleaning it again has made a massive difference. I agitated it fairly carefully for a few minutes in IPA and helped it to dry carefully with my blower while it was flat. I did then dangle for a minute or two more to let final vapours evaporate (sorry@jdm I couldn’t resist!)

Looked much better even by eye and here is the result from a half wind after a few minutes adjusting and regulating.

Whilst I accept that’s not perfect I’ll take that; it’s a 20 year old cheap Seiko with a slightly distorted HS that didn’t work at all last week.

Again, thanks for all the advice and support guys.

In my experience Seiko's never seem to give a good amplitude. I would settle for the results you are now getting.

Not never, see below. It's true that they swing less than Swiss and one has to take what they give.

    • Usually the coiled spring contacts the piezo sounder and the finger spring is the ground.
    • So I checked with my friendly local lab supplier and they can supply the following in 2.5 lt bottles: Tetrachloroethylene (B-Dip) - approx £65 Trichloroethylene (one-dip) - approx £43 n-Heptane 99% (Essence of Renata) - approx £35 Hexane - approx £45 I can't import or buy locally the 'real' products, hence the raw chemicals above. What do you think would be my best option? I'm edging towards Trichloroethylene - I know there are greater health risks, but given the very small quantities used for each treatment and 99.99% of the time it will be sealed in a jar, I think any risk is vanishingly small? This is mainly due to its assumed superior cleaning properties, or from the experience of this group, is the extra cleaning noticeable compared to its safer alternatives?
    • Unfortunately after much investigation, apparently the coil has been discontinued! Shall I get my service guy to try the solder or the conductive paint? 🎨 Final recommendation please🙏
    • Here are the pics of the bridge. Looks correct, but as soon as I screw on the rotor, the watch stops. Video here: https://1drv.ms/v/s!ArG5E62RGctxjokY5ws85BzuJLVakA   Pics. Might have figured it out. I have been working on this watch for a while and since I got it as a non runner in a terrible shape, there was no guarantee that parts were proper. I think the main screw that was used on the rotor was too long, so it was stopping the main train. As soon as I fished out a much shorter and larger headed screw, things were good again. Please celebrate with me.  
    • One-dip or naphtha should be safe, but are you sure it isn't magnetized?  I would also check that.  Although, if that balance is from an Elgin 760 0r 761, I would think it would have a hairspring of non-magnetic alloy.
