Seller claims that this one is a "Pre"-Conquest:

If I compare the Automatic font to the ones in this thread (https://omegaforums.net/threads/longines-vintage-automatics.411/), it is different.
Sold in 1963. Dial looks like a conquest, but the date window is different. Case looks like a Conquest, but case back is different to any Conquest I have seen. So what is it? "Pre"-Conquest or "Post-Redial"?

 

Not a redial but not a pre conquest either. These were cased in US by the Longines partner Wittnauer with their own design and did not carry any Conquest specific trimmings.

 

I dont think we can call it "Pre-Conquest" because the first Conquest was release on 1954. I think call it US model or something like that ^_^

 

As others have already mentioned, watch is legit.

One has to wonder why Menta would sell a full set Longines on the bay instead of his site though.....

 

Thanks!
Again learned something new. Didn't know that WIttnauer changed the design for the US.

 

It had the Longines-Wittnauer reference 69-308 (or 69-308A for the 14k one) and does not measure 35mm but 34,5mm.

 

I always suspected that this was the pre-curser to the conquest

 

And this is why we love OF! A straightforward question and an instant answer showing the massive underlying knowledge base that has coalesced here.

 

All kudos to the long timers here, especially the squirrel lover Dennis for all his sharing and enthusiasm for Longines in times past!

 

The (Longines) All-Guard is generally considered the predecessor of the Conquest.
Learned that from Dennis.

 

Apart from the All Guard, there were also unlabeled versions with the distinctive case and indices.

 

Yes I remember thinking the unlabeled versions were pre-All-Guard as discussed in another thread but they were released concurrently with the All-Guard. Nice trio!

 

I have only seen 1 All Guard, and someone beat me to it
