I have also posted this in the Longines forum, but thought this might actually be my best source of info.
I, like many of you, am afflicted with a type of disease affecting my lust, infatuation, interest, and common senses. My watch interests run the gammot. New, old, inexpensive, VERY expensive....If I am interested and I have the funds at my disposal, I make a spot in my collection for it. Unfortunately, this limits my ability to be knowledgeable about each watch I happen to like and see for sale.
The mystery that brings me to all of you Longines experts is this vintage cal. 13zn.
(sorry about picture quality)
Front end looks good to me. True age to a metal dial. Hands and markings appear correct.
It came to me missing the minute hand. Which I would like to source, but do not know where to begin.
Lets see how she looks from the back.
The column wheel Longines Cal. 13zn. Apparently a highly regarded and sought after movement. Please understand, all I know about this watch I have learned in the 24hrs since purchase.
From what I understand, the 5,43x,xxx serial number would date this watch to 1936. This appears to be the year Longines patented this movement, the first ever flyback chronograph.
The case is staybrite, approx 37.5mm across, 18mm lugs and the serial number inside the press on back matches the movement serial number.
Does anyone know what the earliest 13zn serial number is?
Any and all input on this watch/caliber is greatly appreciated. Thanks!
