How to determine the production year of a Longines watch?

　　As a highly esteemed prestigious watch manufacture, Longines produces models across various collections that hold significant collector value; thus, older Longines timepieces are increasingly prized. How can we locate the serial number on our Longines watch to discover when it was made? Let us take a closer look.

　　Starting from 1867, every Longines watch was assigned its own unique serial number upon completion. Engraved on various parts of the watch, this number helps identify its production era. You can locate this sequence on the outer or inner case back, or on the movement of a vintage watch.

　　Once you find your Longines watch's serial number, you can determine its era of production using the serial chronology below. Naturally, the lower the number, the older and more precious your Longines watch is.
