  1. Cleaned, de-maged and checked h/s for stickyness. Nothing to be observed from that. Did another test you may comment on. With balance removed, I gently nudged the pallet fork side to side to start the release-lock operation. At a couple of close to each other positions on the escape wheel circumference this is not functioning as I believe it should. It all happens fast and is hard to observe but I think there is a ”skip over” where the locking doesn’t happen as it should but locking is happening on the next tooth. As escapement teeth look decent, could this be a case of pallet jewel position on the hairy edge? Sent from my iPad using Tapatalk
  2. Hi, I do appreciate any views and comments over the various timegrapher options available. I have previously reached out for comments and inputs on the Iphone version I still use and the question over the real-time properties is probably a valid one and may be so for a Windows based pc-solution as well. Who can know much about what’s going on under the cover in any such system? In this case I do believe that the Iphone is showing reasonably well that something is not right and that it’s intermittent over a very short period. As promised here are a couple of blow-up’s of the escapement wheel that may (?) be the cause for weird behaviour in my movement. My untrained eye can’t really see anything totally bad (except a lot of dust and debris...) Grateful for any sharper eyes and feedback. Sent from my iPad using Tapatalk
  3. And I was suspecting overbanking but the phenomena is similar at low mainspring tension and much lower amplitudes. I will take out the escape wheel and see if I can take a few hi-res photos to post. Sent from my iPad using Tapatalk
  4. Somehow this got cut from my latest post: The beat error is less than 1 ms. Sent from my iPad using Tapatalk
  5. Hi and thanks, Should have mentioned this but forgot... I actually managed to stop the recording during one of these erratic instances when also the beat error goes crazy. During the ”normal” longer operation periods, the beat error is Sent from my iPad using Tapatalk
  6. Hi, Been servicing a Perfecta 151 movement lately. Runs well with good amplitude but every appr 15 sec the timegrapher traces go wild for a sec or so. I suppose this must be related to something bad in the higher speed parts i.e. Escapement wheel but can’t find anything from visual inspection of the wheel, pallet fork etc. Have attached a screen shot from the timegrapher app on my phone. Any thoughts towards where I should look extra carefully? Sent from my iPad using Tapatalk

  8. Hi guys, GeorgeC kindly offered to send me a spring all the way from Kentucky to Sweden! And the video gives a very good insight in the practises needed, not for just getting the cap jewel in/out but also when, as in my case, the spring has come away alltogether. Thinking back, I believe a major mistake I made was to try to get the spring in with the cap jewel in place. This requires much more force on the one free leg to get it in as the spring also has to bend to fit the top curve of the jewel. That’s not saying it’s going to be easy or succesful doing it the ”good” way ... :-) But I will have to give it a try when the spring arrives! Thanks for all valuable contribution here. I hope there are others out there that can benefit as well. Sent from my iPad using Tapatalk
  9. That makes sense! I was actually trying something in that direction but it felt as if the force needed would be too much. Wasn’t thinking about rotating a blade, which obviously offers more control. Decided to believe that the wide part that you pushed out might be the “hinge” that needed to stay in. Wrong decision obviously. I assembled the movement without the cap jewel and can’t really see that it has too much effect. Dial up/down doesn’t change much and the rate is easily adjusted. If it proves hard to get the spring, I might just leave as is. It’s not like the value will drop by any significant amount...:-)
  10. Thanks, will check on those. And then it’s the escapement wheel that has the end stones, not the pallet fork as I mistakenly wrote. I tried to make a spring from one of the assorted click springs I got from Cousins but that darned thing is really flat and even the thinnest click spring material won’t slip into the grove that holds the spring :-( Sent from my iPad using Tapatalk
  11. Picked up a dirt cheap sea-chief on the local auction site that expectedly turned out fake(ish) with a repainted dial. Movement appeared to the untrained eye decent even though grimy and oxidized, so decided an attempt to service. The pallet fork has end stones with tiny horseshoe shaped springs to hold in place and I obviously managed to break one in two when attempting to re-fit. Havent seen that type before and wonder if anyone can guide in the right direction for spares? And if there’s any best practise out there for mounting these nightmarish things, I’m all ears. The movement is stamped 107 under the balance and there’s a serial no as well. Haven’t been able to id it from that info and grateful for id-assistance. Is it legit or fake all the way?

  12. Hmmm...true. Didn’t note that. Why would anyone remove them (if that’s what happened). ? Sent from my iPad using Tapatalk
  13. Besides what I mentioned previously, the parts look ok. Except...and this is a new thing for me. The roller is cracked along the cylindrical part. Haven’t seen that one before. Unless I get hold of a ”balance complete”, I guess the only thing to do is to say some prayers and hope it won’t fall apart completely? Photo is attached and comments/thoughts appreciated.

  14. You are spoiling us... :-) Let me check the details a bit when I have taken the thing apart. Then I will get in touch over PM. Sent from my iPad using Tapatalk
  15. Thanks, I think you’re spot on ! Nothing on Ranfft for that either but found some pic’s on the web that definitely points in that direction. And Jeambrun sounds french enough... Next step is to pick it apart and asses the damages. The balstaff is gone to start and the top cap jewel as well. Maybe there is more lurking ”in there”...? If I’m really lucky, Rogart has some stuff in his drawers... :-) Sent from my iPad using Tapatalk
