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
i wonder if anyone could offer some advice. I have an Omega seamaster 1345 quartz day date. Working well. However it seems the date is stuck (as shown in pictures) i know the push button at the 4 o clock position is meant to filter through the date? However when pushed in nothing seems to happen. As a result of this the watch works fine but only up untill 11pm it doesnt turn over to midnight and therefor change the day or date. Minute hand works perfectly but it seems i have to change the hour position every morning.
when i turn the crown, hour hand moves fune and after the 12 o clock position changes the day, but date does not moth along with it.
anyone know how i can resolve this safely without removing too many parts of the movement?
