Below is an example of the same reference with an original dial.

I've seen quite a few of these in the late 1990's. Can't remember , who made this batch. Either Bethge in Germany or Soni in the UK. Not well executed.

 

Thanks for the information!

 

You mean batch of dials? Very coarse indeed, in any event.

 

T

he movement have a missing part…

 

Ah, I think you are correct.

 

yes, and It is serious problem coz the movement is the heart, all hand made without cnc,,
even to make one now is difficult,.. and we can do it by CNC, ... however , I won't recommend to collect this piece

 

Mr DirtyDozen , Thank you for your sharing of 3870 ref. 13zn ,

however , It is rare model and I can't see any on sales...
would like to collect one , coz the case size , the stepped case, and the pusher , for me is so attractive , simple and smooth ,,,

 

There are a couple for sale at the moment, that I know of. I can send a private message to you with more information.

 

this is not a original dial , before 1940 , the font is taller and smaller , moreover, the subdial 6 , will be close

nice french-cased 13zn, not an expert but looks nice.
several similar references shown here, I would guess that this would not extract as well, as longines would have used another steel case to export to france.

is the movement number within range? 6.73 mil from what I see.

uploading the photos for future reference,
seller wishes to ship within EU.

 

Yes, 6,73xxxx seems to be a correct number for a 13ZN for the French market. The stamped "M" (see picture) also supports this.

Pretty!

BTW I found the missing part for mine. Of course, it has to me modified to function properly, some tricky work involved...

 

Thanks for the update.
