      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?

      Hello all
      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? 
      Many thanks

    • If the cap jewels are seated correctly and you have not transposed them then the balance is not aligned correctly. Rule of thumb DON'T FALSE ANYTHING. By any chance when you removed the balance cock for cleaning was there a shim between the cock bridge and plate. Sometimes if a new balance staff is changed and it is bit tight a cheats way is to put a thin shim under the cock.
    • I'm not familiar with the tool you are using, but it looks like it is giving good results. Screwdrivers are more forgiving than knives with shapening, to sharpen my screwdreivers I purchased a 240 grit and 400 grit diamond sharpening plate off ebay for just $3 or $4 each and have one an A&F spring loaded screwdriver holder for sharpening and find that gives me pretty good results. The most important thing is using your Loupe to check you have inserted the screwdriver correctly before sharpening. Also if you are removing a chip on the blade you will normally have to hold the blade at 90 degrees to the diamond plate and take a small amount off the end so they screwdriver blade once sharpened to ensure it doesn't bottom out in the screw.
    • Did you remove the cap stones on the balance and fully clean out the old oil? If not the old oil could be gumming up the new oil. Have you checked the pivots of the balance for wear? Checked the jewels for any cracks? Does the anchor snap cleanly from side to side if you nudge it with an oiler with the balance removed?  
    • Wow, thats quite a hoard of Military watches, I own several WWII aircraft clocks and a Navy Deck clock, but have yet to get my hands on any military clocks, thats some serious practice you have had.
    • I realize its an old thread but deserves a bump, its pure gold! Thank u all for all informatin. I myself have a Elma super Elite and  ive been struggling with the cleaning result. I think i just expect too much out of it
