An interesting new acquisition that may look familiar for those of you on Instagram. Quite a unique example, but very much at home in my collection! Cal 23M from the mid 40s. Waiting on extract.
Got this information from Longines:
"reference 2326 and the order number 20960. It is fitted with a Longines manually wound mechanical movement, caliber 12.68Z. It was invoiced on 14 September 1940 to the company Ostersetzer, which was at that time our agent for Italy."
I have seen some other reference 2326 that shares the same case as mine but I also stumbled across this text about the black Serbian: https://www.standbycomlda.com/buy-a-watch-with-me-the-story-of-the-black-serbian-part-2/
And stated this 37,5mm is reference 2326 and batch number 20652, it does seems odd a 32,5mm and 37,5mm case shares the same reference?
