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??
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.
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.
Just got to think about it when I read the part of letting the power down, these movements have a stop function in the winding.
If you just let the barrel go in an uncontrolled way you might break the stop finger. I often find these ratteling in the watches from now and then, and I can't see it in your picture of the barrel bridge either.
