The OP describes it as manual wind in their sales listing

Since this example has an American-made case, it would not have a Longines reference number associated with it. There may be a model name in an American catalog or advertisement, but most collectors today would refer to the watch by its caliber. If I had to guess, I would say that the caliber is probably a 23Z. See a similar example below.
