      Hello watchmakers!
      Now I am working on a vintage bifora movement, Bifora Cal.812.
      I have ruined the hairspring while trying to fix the position of it on the balance wheel to 
      adjust the bit error. I am searching for the balance complete or just the hairspring on ebay and other 
      suppliers but I haven't been lucky. May be I need other keywords for my search.
      Could anyone help me find the part I need??
      Thanks!

      Hello. 
      I am working on this  vintage A.Schild movement and a jewel on the wheel bridge.
      It is a jewel for the 3rd wheel but is cracked so needs replacement.
      I measured the outer and inner diameter and they are 1.2mm and 0.17mm respectively.
      Could any one help me find the replacement for this jewel??
      I am always grateful for your help.

      Hello. Dear watchmakers.
      I have a very old timepiece from Rolex that I am about to work on..
      From googling, I found out that this is called "trench watch" that might had been used during WWI or any other war in that era ( 1910~1920)
      However, I could not figure out the reference no. of the movement. All I know about the movement is that it is 29mm in diameter and has 15 jewels.
      I am actually looking for a replacement movement for this watch since the mainspring must be replaced due to damage.
      Plus, I am also looking for the rachet wheel with "Rolex" engraved to replace the existing one.
      I have found similar movements on the web(the third photo added)  but click part was not the same.
      I wonder if the one with different type of click would have parts that are replaceable.
      To sum up, my questions are
      1) the reference of the movement.
      2) how I can get parts or the whole movement for replacement
      3) does a movement with different click type would be suitable for replacement.
      Thanks and  I wish you a great day.

      Hello.
      I am now working on a vintage "trench watch" movement from 1910s that I mentioned before with a question regarding identification of the movement.
      (I still haven't got the exact ref. of the movement.)
      As I was disassembling the movement, my screwdriver slipped and broke one of the parts that function as a spring for the click.
      I tried looking for replacement but I am not sure what I should look for.
      Also, one of the jewels on the  wheel bridge is broken so I need a jewel as well. 
      Could anyone advice me on how to find the correct part for click spring and the jewel for the wheel bridge??
      **Could the click spring be put back together??
      Thanks. You are always of great help.

      Hello. I am working on a vintage piece but I could not find the name(ref no.) of the movement.
      Could anyone tell me the name of this movement?? All I know is that it has "AS" written on the mainplate.
      Thanks!

    • are we talking about round wylers?  the special crystols are hard to find. there were several colors.     vin
    • I'm going to have to do something. One decent desk lamp and bulbs high up in the ceiling are not enough for me.
    • You are most welcome.
    • Thats  a poser,  what I had fitted to the bench at on time was a four in line which used halogen bulbs the same thing uses LEDs now and fitting that up with some 2by1 and made colapsible so that it folds up. the multiple light array should go some way to removing the shadows as the lights strike at different angles,  if it has a decent base a G clamp will fix it to the table/bench, food for  thought.
    • Yes, something like that might do the job. In many ways similar to the goose neck lamp I’m looking at. If only I knew what I need. The light in the picture I posted is very good (not the small one), it’s the fact that it is slightly in front of me hence the shadows. I can move it right above what I’m working on, but again, there will be shadows elsewhere because my hand and head will get in the way. I’m starting to think that a floor lamp next or close to me will be the best solution, casting the light from opposite direction. A head torch would be perfect but I don’t want to sit there with it on for hours. When I look at Mark’s oiling videos (jewels) it’s so clear, yes it’s a lot more magnified than my 12x loupe but there are no dark areas.
