I am looking for vintage Longines catalogs of any year, but I can't find any. Do you have anyone you are willing to share;
It would be helpful if you could state what model and approximate year(s) that are of interest too you. Regards, Tony C.
Well I am interested about any catalogs that contain the Ultra-chron models so the timeframe should be from 1967-77.
Hi All, Looking for a catalog for a 1946-7 Longines that has a 23M movement (#7386238) and 5863 model. Also, what does the 356 number on the caseback represent? Calling @Tony C. !
I'm not sure if the rule of thumb extended to Longines-Wittnauer watches, but in Switzerland the numbers there would be the last three digits of the movement serial number.
Sorry, but I don't believe that I have any catalogues (or images) from that period. Very nice case, though!
It's a unique case number but not a serial number? I'm not sure I understand, please elaborate. Do you mean the serial number of the movement?
That's what made me want to buy it! I did find a similar one here (though that one appears to have had its dial cleaned, which lightened up the background but lost some of the print). I didn't find another on the web with that case.
Yeah, I found your thread five minutes later https://omegaforums.net/threads/incoming-ultra-chron.18100/ Thanks!
I thought the unique case number went on the underside of one of the lugs? At least, that's been the case (pun not intended) with every Swiss cased Longines I've had (admittedly a rather small sample). Unique case number on a lug, and last portion of the movement serial inside the caseback under the reference number.
Certain references have a unique case number on the underside of one lug that matches a number on the case-back. This is incorrect.
Thanks! It's a 23m, very clean, and from the early '40s. And I agree that double-signed Longines are uncommon.
