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?
Had to get new winding stem to an Omega cal. 342 , beacuse not original crown.
Got an replacement from Ronda, but does not fit.
Tried to fit the stem yesterday, but Im not able to get in in right in the movment.
The original just go right in every time, but the new Ronda stem will not go properly in.
Are there anyone that have some ide why this not fit?
Can the notch in the stem where I have put red arrow have somthing todo with this??
Its slightly smaller on the Ronda stem... se photo
Wide range of restorative attempts and I say good job, too many to master all though.
I buy more selectively focusing on the work you enjoy tirelessly.
