      Hello. 
      I am about to work on a Omega ladies automatic watch.
      I found out that the axis of the rotor is out of place and shakes up and down.
      What could be done in this situation?
      Thanks!

      I have an old Waltham pocket watch movement which is missing the impulse pin (roller jewel).  I have a limited number of actual jewels and since this is just a practice movement I thought I'd try to make one out of brass.  I've seen this several times in old pieces--usually a very sloppy job.  So I got some brass stock of the same diameter as the "D" in the roller table, filed it and burnished it to a high gloss.  Then I took a small, very fine diamond file and filed it half flat to form the "D"  I then polished the face using progressively finer sandpaper on a steel block.  This works fine--so far!  Problem is separation of the piece from the stock.  Again I used a small cutting file to do this but it doesn't leave the end very pretty.  So what I've done so far is to fit the good end into the roller table.  I then plan to shellac it in place and see if I can very carefully adjust the length and clean up the end.  Has anyone done this before?  Any suggestions as to how best to do it?

      Working on a Omega Cal. 613, have done service, and watch performs well on the time-grapher, but when put dial and hand on, I can see that the

    • Well, I don't know the official terms because I'm only an amateur. What I meant saying "full wind" on the 1575 (which is of course an automatic) is: I turned the crown about 40 revolutions so that I'm absolutely sure the mainspring is in the "slipping area". Thats "full wind of an automatic" for me.  Status update: After 30 hours the watch is 11 seconds ahead of the atomic clock. So the "about +9 result" of the timegrapher seems to make sense. I will observe until sunday evening if this is continuing. 
    • It was back in the 70's & 80's when I was a watch/clock maker. I'm still learning something new. Thanks. 
    • It depends on the mov't. 7S26 and its direct predecessors don't. All the others do and you might be surprised to learn that they hack also.
    • Not a great picture. Taken at the bench with the lights and cellphone.  Elgin Grade 430 3/0s in a jobber's case, Elgin 714 Shockmaster, and  Wittnauer Revue 73.  The Witt dial was shot so I just stripped it down to metal and did barely enough polishing the make it un-ugly.   I didn't think it was valuable enough to justify restoration.  Probably all will go to the auction site now that I am done with them.   RMD
