  1. I've had this watch longer than any other. Sentimental to me. Always been a work in progress. An ongoing problem has been there doesn't seem to be enough power to operate all the functions properly unless I keep pressure on the crown, essentially loading the mainspring. (Which I have changed several times) Have cleaned, checked for interference, changed components, with no luck. Have even run the basic movement without any additional complications to no avail.
  2. Figured the pushers out.The silver part is the inner piece on the inside of the case. The brass piece with the o-ring is the outer part that gets pushed. Obviously the spring sits in between. The silver end is a tube that pressure fits over the outer piece. Has a knob like end that keeps it from slipping through the sleeve insert, which has a large diameter on the outside and a smaller diameter on the inside. That also keeps the spring retained between the 2 pieces. Sorry for the poor quality.
  3. tried that with some lube and an oiler. Didn't do much. Going to try the cleaner and see it it loosens things up. Thinking more of a rust issue with the springs maybe. I can push them in but they get stuck in that inward position. Thanks for all the input.
  4. Assuming the tube size to sit outside the pusher?
  5. How would you get the cleaner/lube between the sleeve and pusher shaft where I assume there is a spring?
  6. movement IS out of case. The last 2 pics are from the inside looking at the pushers. BTW no C clip either
  7. Have a couple of sticky pusher on a eta 2892-a2. Revue Thommen. Cant figure out how to remove them,
  8. Thanks. Talking through and getting great advice goes a long way. Will adjust the hs tomorrow. thanks again!
  9. Still tinkering. Continuing the assembly. TG shows improvement.
  10. Changed balance and hairspring. Removed pallet ok. New video. Rotation almost 540(270 ampl). Getting there 20200324_171343_002_1_2.mp4
  11. Using your diagram, rotation measures from the table jewel centered between the pallet horns which is centered between the banking pins. That gets close to 1 full rotation. 20200324_124006_002.mp4
  12. When you say impulse pin are you referring the to the roller jewel. Also, you are using the banking pin center in either case correct? I then understand the balance rotating twice if using the end rotation contact with the outside of the pallet horns. Took a new video with a partial assembly. Rotation appears approx 3/4 .Also pic of timing. Not reading very well as you can see
  13. You mean overbanking? I haven't observed that in a running state. When I manually rotate the balance it takes 2 rotations in either direction for the balance to hit a stop. Now that may be it hitting the outside of the fork horn. I'll have to check that Thanks
  14. Yes I replaced the mainspring with a correct piece. I also removed all chromo functions to ease the drag on the train movement. That's when I observed the over rotation. Although the movement is still very slow. I can see the pallet fork banking from pin to pin. Need to take a closer look, but it appears the fork rests on one of the banking pins and seems to hit and bounce off the other. It's torn down/cleaned and ready to check components. Plan to assemble train only, and go from there. Thank you.
  15. You are reading correctly. I posted a short video of the balance rotation. Not the best, but I will make a better one later, along with a video of another 72c I have that keeps excellent time to compare.. May be dumb question but.....If the physical rotational degrees of the balance are twice the amplitude degrees, what is the measuring source for the amplitude degrees?
  16. Thanks.will give it a shot. Some files may be too large. 20200319_190833.mp4
  17. Having a real problem locating how to respond to posts. I apologize to all that responded, and thank you for your input. I recorded the rotation in super slow motion. I would post if someone could tell me how. The 2 full rotations are done manual without the hairspring. Stop to stop. In the slow motion video the balance rotates about 1/4 past a full rotation of the balance. The breguet hairspring is fine, and the balance rests perfectly between the pins.
  18. Thanks for the reply. Sorry it took so long .Learning the site. Didn' think of the plate. Concentrating on the roller table. Just don't understand the 2 revolutions of the balance to lock. BTW the cousins info is very helpful, Thanks again
  19. Have had this piece for many years and am having issues. Just tore down and cleaned. Before I correct a few simple issues, there's a problem I cant seem to get a handle on. I noticed the balance rotates more than 360 degrees, and the movement is loosing time quickly. I had replaced the mainspring to help with the slow time, and that's when I noticed the over rotation. I had removed all chrono functions to eliminate possible drag, but that didn't help the timing. I assumed the table jewel was missing, but it is still there. Next I removed the hairspring and mounted the balance wheel to manual rotate. It appears the balance rotates 2 full turns before the pallet fork banks to the opposite pin and stops. Assuming that accounts for the overbanking when its running. Can't figure out why the balance is rotating 2 times. Could it be the roller table is wrong size? I do not know the spec for the 72c. Greatly appreciate any direction. Thanks Dennis
  20. Was looking for a new forum and found this from the videos on utube. My names Dennis. Been working on watches for a dozen years or so. Partial to mechanical complications.
