  1. I would also guess broken mainspring.
  2. Oh, sorry. I understood you had cleaned and re-used the old spring.
  3. You are testing it correctly I think. It sounds like the brake spring has set and become too curved. It needs to be straightened or even curved in the opposite direction so that it grips the outer wall of the barrel more tightly.
  4. My money is on the mainspring too. You like changing mainsprings, don't you Charlie? I like Andy's option 6 too, bit only because of the comedy. That is a lovely looking watch. It's going to be a gem once you get it up and running, I'm sure. Quite jealous actually.
  5. That S-emblem is really a 5-emblem, by the way. The Seiko 5 line is a rabbit hole all of it's own.
  6. I just looked at your latest photos. The pivots look OK to me. I agree with John above. That is an odd place to pin the hairspring. Have you tried it pinned at the end?
  7. Welcome Charles. That's my aim too, to look after my own watches. You have come to the right place.
  8. What sort of references are you looking for? I'm guessing there were no instructions with the dial. However if you identify the dial fixing screws on the movement you want to use it should be easy to work out which feet to remove.
  9. I think Deggsie's assumption that the rate is extremely high is correct. Like I posted above, I can get a similar looking trace by manually setting the rate in my W1900 to 17786 bph but analysing a 18000bph movement. I'm betting those wide-spaced dots in the second picture are not horizontal traces, but almost vertical. Only IFELL can tell us for sure. A check of the rate over 3 min. or even 10 min. won't hurt and will provide an important clue. The Weishi 1900 doesn't output the true sound of the movement, unfortunately. No scope mode either. Graph type B will also show steep lines, if the rate is way out. I agree the sound would be useful. Maybe there is another way of recording it?
  10. According to Ranfft, this movement does run at 18000 bph, but the traces are what you get if you are slightly out on the setting. For example, I've got a 18000 bph movement on my Weishi 1900 here, and I set the beat on the machine manually to 17786 bph. The display looks very similar to the second picture in the original post. Doesn't help with the problem, but interesting all the same.
  11. I would have suggested knocking, but if your timegrapher is to be believed, then it's not that with only 229 to 241 degrees amplitude. Maybe the hairspring is rubbing? Is it the same in all positions? What did you do to slow down the balance? Out of interest, why are you running your timegrapher on monochrome? It's a Weishi 1900 with colour display, isn't it?
  12. These are Kif Duofix I think, and Seiko have a similar design called Diafix. Here's a video showing how to open and close them. As Marc said, the trick is to not remove the spring, but I made the same mistake a while ago when I first encountered them, thinking they are similar to Incablock, and you bend the legs inwards. I had nothing but trouble with them to be honest, even after I'd understood the right technique. Lost springs, lost cap jewels, broken springs. It is also very difficult to find spares. In the end I replaced the entire bridge, because I couldn't get the spring back in in one piece. Incablock is a dream by comparison. Here's a video showing how to open and close them. He gets down to business with the correct technique after 3:30, but the bit you need starts at 12:15. Good luck!
  13. Maybe the autowinder is magnetised? the rotor is a big lump of metal. Maybe it only needs to be lightly magnetised to affect the amplitude and thereby the rate (and the beat too, by the looks of it). I can't see how else the autowinder would affect amplitude, as it's on the passive side of the barrel.
  14. Congratulations on your first success and welcome to the forum. You can learn a lot as a beginner here. Don't be afraid to ask (if you can't find what you need using the search function). I have had nothing but positive responses to my questions, which isn't something you can say about many forms.
