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.

      Blew it with a coil

      By watchweasol · Posted

      Hi. Breaks like this can br fixed with conductive paint like the paint used to repair a car  rear screen heater. I have used it successfully, you don’t need much and unlike solder there is no heat 6020A-1.pdf

      the problem with vintage watches and yes quartz watches can be vintage is availability of parts will be a problem. I have a link below where we can cross reference the coil and  I was hoping for more. Another problem for vintage parts are everyone on the group gets used to ordering from online. Conceivably the physical material houses that still exist out there might have the part and you'd have to reach out to them and see if anyone has one. this is because they don't list every single part that they have online with the exception of cousins where everything they do is online work just doesn't exist but the other material houses can have stuff not listed. Otherwise just set up a search on eBay and sooner or later it will possibly show up if you're lucky.   http://cgi.julesborel.com/cgi-bin/matcgi2?ref=SEK_6020A

      Difference between AS 1686 and ST 1686

      By Waggy · Posted

      Maybe a little off-topic, but it still amazes me that most people (and myself before I got into this hobby) don't realise that the movement of their watch was (in most cases) not made by the name on the dial of the watch. This is especially true of many 'fashion' watches which use the cheapest of cheap movements ($4 each) which are completely out of proportion to the overall cost of the watch ($++100s). Usually the actual manufacturer is stamped somewhere inconspicuous on the movement, usually around the balance, and this is what you need to find so you can locate spare parts or servicing manuals etc. This is like buying a top of the line Rolls Royce Phantom and learning it has a BMW engine..... oh wait a minute, it does! (6.75-liter, 460-horsepower BMW V12 engine - reference)
