  1. Hey m1ks, I don't know if highly unlikely - but I was thinking along similar lines. -Paul
  2. I didn't anticipate this. After centering the impulse pin (visually) - I don't see a material improvement in beat error. BUT - the weird noise is gone! In as much as I can't center the impulse jewel any better, I guess I'll have to live with the beat error. But I do feel better that the strange (to me) noise is gone. It sounds perfectly healthy. Amplitude is only around 250. Not great, but I think for a vintage watch, 250 is in the acceptable range.
  3. So, now with the pallet fork out - I can see that it rests a bit more off center. It's still not a bunch. But instead of being slightly off-center - I can see the impulse jewel resting at the left banking pin (left as look through the banking pins toward the balance staff). And of course, I see a more significant misalignment with the mark on the balance wheel. I tried to photograph the impulse jewel looking through the banking pins, but couldn't get a usable shot. Sorry. So, I will work to get that centered up and then reassemble enough to recheck the beat error. I expect that I should be able to get it close enough just by centering between the banking pins. Will update with results. Again - thanks to all that take the time to post and share their knowledge. -Paul
  4. Yeah, my inexpensive timegrapher seems to hear everything it needs to suit my purposes - but it doesn't "play" what it "hears". It does make a nice fake/generic tic based on the beat rate.
  5. That's a good idea - to try to record the noise. I suspect that will also be very challenging - as it's not something you can hear without holding the watch to your ear (in contact). I'll see what I can do.
  6. Thank you Nucejoe! Not sure how easy it will be for me to observe that, but I will try to have a look.
  7. rodabod, Thank you for those comments. Anyone hear similar from the Omega 266 family? (is it common for them to make similar noises?)
  8. So - a little more info. I didn't do any disassembly tonight, but I did have a little time to pop the back off and see what I could see. First, I did indeed find a small (VERY small) dot on the rim of the balance wheel where the hairspring stud points. And it looks to be pointing at that dot - but the distance between them makes it somewhat hard to tell with any degree of accuracy. With no power in the mainspring, the palette folk comes to rest very near the center of the banking pins. Perhaps this is to be expected when the beat error is less than 2 ms? 2 ms sounds like an enormous beat error to me - but it may not be many degrees off center. I think it would be best to eyeball it with the pallet folk out - so that I can get a clear view of the impulse jewel - and the pallet fork won't influence where the jewel / spring come to rest. Lastly - no excessive play in the balance staff. Again, thanks to everyone for sharing their knowledge and ideas. -Paul
  9. John, Thanks so much for all of the additional info! I believe the video being referenced is "How to align the hairspring to set the watch in beat" If the link doesn't work, you should be able to find it by title. -Paul
  10. Hum... Thanks nickelsilver. I will keep that in mind. I haven't heard anything like this before, but The overwhelming majority of my watches are ETA 2824's (or similar). So, not a very diverse sample. I'll go after the beat error and get that corrected - and reassess from there. -Paul
  11. Guys, Thank you all for your input. Given my schedule - it may be this coming weekend before I can spend any time with it to answer some of the questions you have posted. I have ordered a balance tack though. So will have available in a few days. Planing to correct the beat error first - since the cause/correction is pretty definite. Then see if the noise persists with that correction made. As always - many thanks to all that share their knowledge and take time to post! -Paul
  12. m1ks, Thanks so much for your response. No problem stripping things back down to wherever necessary to regulate the beat error. But not sure the equipment required. I'll have to investigate that some more. The variance in beat error was by position. Not regardless. Max amplitude is about 240 degrees - so, I don't think that would make over banking a probability. Plus it's only noticed when the balance staff is not vertical (not dial up or dial down). Will have to do some disassembly to investigate. Thank you! -Paul
  13. All, Some of you will know that I have been working recently on a vintage movement. It's an Omega Ca. 266. from 1954 according to the seller - presumably based on the serial # from the movement. I decided to give the movement a full service - as I didn't know the service history. Which after stripping down the watch, it was apparent that it had been serviced in recent history. As everything was incredibly clean and all lubricants still clean and fluid. Of course, I wouldn't have know that without stripping it down. After reassembly (following cleaning and fresh lube) - most everything seems to be in good order. But I can hear a funny (odd) "ting" noise in the heartbeat when the movement is positioned such that the balance staff isn't vertical (isn't dial up or dial down). I assume that the noise is coming from something in the balance. But I don't see anything too weird on the timegrapher. Other than too much beat error (1.2 - 1.8 ms depending on position). So, two questions (I am assuming this isn't normal or healthy) 1) What would you check for? 2) How does one correct (or improve) the beat error on a balance without a beat correction? I am guessing that the hair-spring would need to be loosened at the stud. Then position the balance to the center position and tighten the hair-spring stud? Or something like that. I am seeing about 250 degrees amplitude dial up or down. -4 sec/day. Down to about 210 degrees with the balance staff horizontal. Not much variation in the timing. Worst position was -9 secs. Most about -4. Best +1. If I hadn't put the movement up to my ear, I wouldn't have any idea that something was "off". -Paul
  14. Somewhat as I expected, the Bergeon 30209 did not disappoint. The broken piece came out without a fight.
