What did people do with this watch?
What was the purpose?
Who was it assigned to in the French Navy?
Was it for soldiers or was it for administration staff?

Well, I’m guessing here, but I think they used it to tell the time.

and a super nice macro shot @septentrio.

@Seiji I believe Zaf was looking into it at the time he was working on his new book about military watches.

Hi Seiji

Not sure if you already found your answer (With all your knowledge on Longines and all the research you're doing I guess you already have some information 😀), but I'm sharing what can be found on a French source that I personally like reading articles from :
https://chronographes.net/2018/05/12/longines-mn-ref-5774-dans-lombre-des-stars/

Basically it is said to have been ordered following 2nd world war by the military French Navy and delivered between 1946 and 1948.

And to your point, it was supposedly then for officer only :

In French : "Qu’on ne se méprenne pas pour autant : la montre que nous présentons aujourd’hui n’est pas un de ces modèles qu’on appellerait aujourd’hui « tactiques », c’est-à-dire conçus pour les opérations d’infanterie de marine voire pour la plongée de reconnaissance ou de combat. Pas du tout. Destinée aux officiers de marine, elle devait cependant supporter l’humidité, résister aux chocs, être lisible, fiable et d’une précision sans faille. C’est ainsi, sur un cahier des charges grosso modo bâti autour des ces critères, que la Marine nationale passe donc commande à la manufacture Longines d’une montre à cadran et aiguilles lumineuses, boîtier acier, fond acier vissé."

Google translate (sorry I'm lazy) :
"Let there be no mistake: the watch we are presenting today is not one of those models that today we would call "tactical", i.e. designed for military operations. marine infantry or even for reconnaissance or combat diving. No way. Intended for naval officers, it had to withstand humidity, withstand shocks, be legible, reliable and flawlessly precise. It is thus, on a specification roughly built around these criteria, that the French Navy places an order with the Longines factory for a watch with dial and luminous hands, steel case, screwed steel back."

Have a good weekend,

And thanks for all those posting those watches. I don't own one but the more I see them the more I like them.

These are nice watches. I think I ran into a similar situation with the U.S. Army Omega that is in many ways similar situation. @YYTIN, your article is nice reading, thank you for the link.

Actually, I should correct the record— Jennifer Bochud in the spring of 2020 reached out to me as she was doing research for a heritage reedition of the Marine Nationale.

We had a few email exchanges and I put her in contact with Zaf and a collector friend who has bought many MN over time.
She later informed me, in an email dated June 2, 2020, that the Longines archive had not retained any information on the specs provided for the Marine Nationale which could shed light on who was supposed to use it and how.

In that email she said:
«Malheureusement, nous n’avons pas retrouvé le cahier des charges de la MN dans nos archives. »

My translation:
« Unfortunately we didn’t find the prescribed specifications for the MN in our archives »

If anyone can find out it would be Zaf. I know he has contacts that used to be high ranking in the French defense organization.

Great article, though I found that the space between the lugs/horns on mine (invoiced July 1947) is actually 11/16th inch or 17.46mm.

Here it is on a period-correct 11/16" Forstner "Adjustit" Krementz/Bonklip-style bracelet (patented 1946) which fits perfectly:

For the record- the Freéch article posted above is using
without credit the typology — and pictures— identified by @DirtyDozen12 higher in this thread.
I know he is the true author of because he shared it with me privately in late 2017 or early 2018-, but which I know he also shared at the same time with at least another French collector I’m aware of.
So It’s quite clear to me that his research unfortunately was leaked and misappropriated in an annoying and inappropriate fashion.
I’ll try and locate the email in question to set the record straight (unfortunately cannot do it this very minute).

Hello everyone!

Here’s number 38, I recently acquired it through a Vietnamese vendor.

Any feedback is welcomed, do share your thoughts about it!

Currently waiting for it to arrive, my only concern is the number 8 that’s upside down.

Thanks to everyone!

Thanks for sharing! I updated the table to include your example. Number 38 seems to fit as the serial number of your watch is exactly 80 earlier than another example with number 118 (7'305'394 versus 7'305'474).
