Hey guys, sorry in advance for the quality of the picture but my question is essentially related to the consistency of the lugs/dial with the movement. The seller claims this is an original 13zn and the movement is in fact a 13zn. This is a Fab Suisse dial with the fancy lugs that I think are more commonly found on the 30CH. So I am basically afraid that this is a recase or some franken-thing of the kind. Any thoughts? Thanks a lot in advance for your help
Looks like a French-made, 30CH case. Must see better photos from back and inside but probably a watch to avoid. Any archival info regarding original case material, reference, country?

I am working on additional photos to share, but for better or worse he is a very unsophisticated seller...but so it is possible to fit a 13zn on a 30ch case right?

I do not know for sure but the dimensions of the movements are very similar.

Condition of the movement is excellent, which does not immediately suggest a storied past. Assuming that the extract confirms its delivery to France and specifies a locally-made case, all is probably well.
Thanks a lot for your thoughts. Serial number is 7136133, which I believe is 1946 and therefore could be correct for a 13zn. Will ask for an email extract and let you guys know!
I have no idea whether it’s correct but posting it here for the record because I find the case beautiful. Supposedly reference 5161. The seller did not post case back pictures.
Hi all,
This is my first comment here. Joined yesterday but have been reading this whole thread, 48 pages all the way through. Very interesting reading and thanks alot to all who have been participating with their knowledge, very much appreciated.
Well, the main reason I´ve been reading all this is that I reacently came across this Longines 37,5 mm, 13zn, 5415, batch no 23485 delivered to Sweden in november 1948. Sn 7309xxx. Matching two digit no on case back and case middle under lug (19). A real project. 😀
As you can see in the pictures it has seen better days and a few parts is missing. Movement have been serviced but as you can see, operating lever with its hook is missing. Also, chronorunner hand and one pusher is missing.
Anyway. I wonder what you think about the dial and hands. The lume is heavely worn and missing at a few spots, same colour as the minute hand lume.
White register hands, were they originially painted white?
Despite the fact the lume is partly gone I will just keep it as it is.
If original, I assume this dial is quite uncommon?
What are your thoughts?
Cheers!
As @Radiumpassion stated, the dial is original and very uncommon. Reference 5415 is desirable in any, original configuration due to its large size and waterproof design. But, as you may have gleaned, black dials are especially prized.
This watch is certainly a worthwhile project. Finding an operating lever should be possible. Locating a pusher and correct hands will be more challenging, I imagine. I say hands (plural) because the minute hand is not correct. Notice how the aperture for the luminous material on the hour hand is rectangular, whereas the aperture on the minute hand is pointed at one end. I also believe that the small, register hands were not originally white. Earlier, black-dial Longines could be found with white hands but I would expect an watch from 1948 to have polished steel hands.
Thank you for posting these great photos. It is always interesting to see the back of a dial.
Thanks alot @DirtyDozen12 for your input. Yes, not very common in general when google "5415" and adding "black dial", well, not many resluts on that for sure.
Regarding parts, all of them (original of course) are on the way. Hope they will get through the mail safely. Also, regarding the hands, I´ve been thinking about the hour and minute hands but I haven´t been sure witch one of them that is original. Thanks alot for clearing that up.
A question. Not sure about the "batch number". Does it say anything about the watch regarding any details?Also, are ther any figures on production rates for these fellas?
Cheers!
"Batch number" (now "order number") refers to an order made by an agent in a particular market. The order would have been for a specific reference so there could be many, correct order numbers for a given reference but not the other way around. Sometimes, an order number that corresponds to a serial number is accessible in Longines' archive. This can assist to confirm the originality of a given case with a given movement. Also, the order numbers increase over time so a very early order number that is paired with a later serial number can serve as a red flag.
Unfortunately, I do not know of any production figures for these watches. Longines is not keen on discussing this matter either.
Ok, thanks. In that they could pair this sn with this case back batch number is always something then. And the next number, in this case 19 is just the 19th watch in that batch then?
