Hola Longines OFers!

Been awhile and have paused on my collection for quite a while now as it was getting a little out of hand costwise and with rising costs of living, but saw this 13zn at a pretty reasonable price that may make me make an exception.

I'm more of a dial guy in terms of eval and going through the first 15 or so pages of this thread did not see any examples with the Longines logo in san-serif as this example has which is bringing me to think redial. But i do know that that logo was sometimes used in the 40s as well so wanted to get some of your thoughts and hopefully blessings before I pull the trigger.

Have no idea how to evaluate watch movements and so far for all my conquests and flagships have been relying on the right movement ref etchings so would appreciate any help!


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.

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

Thanks!

It is now mine ::psy::

I will take better pictures and ask Longines about it. I'll report the results. If it was imported naked or recased from steel it may explain the various plating colors?
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

Hi, thanks very much for your input. I have also never seen such a two-tone dial on a 13 ZN so I wonder about the short hands. The dial has copper toned feet. The Longines font is quite large, too large for this 1930s period? And yes, the comparison with your example shows a polished case, I see.
this is not a original dial , before 1940 , the font is taller and smaller , moreover, the subdial 6 , will be close

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

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.


Pretty!

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

Here are some photo collages, well (or badly😅) focused on sub-dials (all original), which could help to evaluate the originality of a "13ZN-12 sommatore" dial (ref.5161 or 5966).💪🤞

Thank you for sharing these. I do not recall seeing an example with a black dial before. Do you have more information about this example? I made some similar collages a few years ago (all photos from a Monaco Legend Group auction). I have added them below. Hopefully, all original!

I think very few 5161s were made with a black dial...In my lifetime, I’ ve only seen one (even held in my hand), in Madrid many years ago.
I am asking the owner if I can post a picture, and if he he allows, I will.👍
