  1. I will try to find a material and fabricate a replacement. Do you know from what kind of metal is that spring made of?
  2. Hello everyone Does anybody have for sale a SWEEP SECOND FRICTION SPRING FOR LECOULTRE CAL. 450, 468, 470, 478? I have to replace a broken one on my personal watch. If you do have one please let me know. I will attach an image for your reference. Many thanks to all Doreen

  4. Here is the watch back on it’s case...a beautiful watch indeed.
  5. I finished to replace the main spring and I’m pretty happy with the results considering the fact that is an old movement. I know it is far away from being perfect and It could probably get a little bit of better results with the amplitude, beat error, etc. if I will adjust more the hairspring. As I mentioned before the hair spring was twisted/distorted and it was not parallel with the balance wheel cock. That affected tremendously the good working condition of the watch(timing, beat error, amplitude). I did a lots of adjustments to the hair spring and I set the watch properly in beat by aligning the roller jewel properly between the two banking pins. I diced to leave the watch the way it is at least for now. I will attach a few images with different watch positions on the timegrapher. Thank you all for your comments, advise and help.
  6. I have to admit it is a intense back and forth work and a lots of adjustments and twisting.
  7. I actually found online several lift angles lists very useful. Thank you
  8. As I’m pretty sure you know they are so many different ways to put a watch in beat.I will post two links showing the two methods that I use to correct the error beat in this particular movement. I hope I’m not crossing any forum’s rules if I post the links to the videos here. I used both methods in my case because the hair spring was twisted a bit. To answer to one of your direct question if I “visually verify if the watch is in beat”; yes I did verified that visually. The beat error did not actually change because I cleaned and oiled the movement ; the error beat had to be corrected by using the two methods from above.
  9. I corrected the beat error from 2.2-2.7 to a 0.5-0.7 I know is not perfect; anyway I consider it pretty close to be accepted like that. The problem is now, after I correct the beat error the amplitude when down dramatically from 220 to 155-165. Perhaps after I will install the new mainspring will rise again. It is pretty tricky to adjust all that. I will keep you posted.
  10. Thank you for your response and help. It is indeed a great list with a lots of lift angles.
  11. I think you are quite right, it is very tricky indeed. I just hope that after I will install a new mainspring and I will adjust the beat the number will increase a little bit more. If I will get it around 230 -250 I will be happy considering the fact that it is an old movement.
  12. I noticed the hair spring was a little bit twisted. I ajuste a little bit one of the coils that was not parallel with the line curve. After adjustments it is a little bit better on the timegrapher now. Now the amplitude is a little better. I’m sure it will increase after I install the new mainspring. I still have to put the watch in correct beat.
  13. I also finished cleaning the movement. I hate it now on my timegrapher. The beat error is to high 2.2, that has to be correct too. low amplitude 183. I ordered a new mainspring that will arrive soon. I will change the mainspring too. I will keep you posted after the proper correction are made.
  14. I just finished up the case ...cleaned and buffing up a little bit; not polished. I installed a new crystal too. Very pleased with the results.
