Since you know so much more than me about vintage watches , maybe you know what model and year this is?

 

No particular model. As you have probably read on the forum by now, the year of manufacture can be determined most accurately if you show a photo of the serial number. Otherwise we are guessing based on style, and the best you will get is a rough approximation. It appears that the minute track has been repainted.

 

On the movement S/N 81306xx and L12
On the caseback is the number 5413 11 638

 

And the picture

 

I guess you probably mean 12L (not L12), which is the movement caliber. The watch is from about 1950. If the watch has sentimental value to you, you may want to get a free Extract from the Archives by following the instructions on the Longines website regarding information about the history of your watch.

 

Style-wise I would say late 50’s- early 60’s, and as Dan said- that minute track is a bit- wonky.

Edit- totally 50’s- maybe leaning early 50’s. It’s probably around 33mm as well.

 

Ok, what should i search for to get the value? its 31 mm

 

I remember having the same problem when I was checking the prices for my dad’s Longines 990.4933 (cal. L990.1). To my novice eyes, the L990.1 caliber looks pretty impressive and beautiful. Is it safe to say that vintage Longines just aren’t as collectible?

 

You can google Longines 12L and search for a similar dial to get an idea of value. Unfortunately, 31mm is pretty small by modern standards, so the demand for a watch like this is pretty limited.

@Lotus_Eater8815 i wouldn’t necessarily say that. I am a Longines fanatic and I know quite a few others. The brand is somewhat hurt by its positioning in the Swatch Group stable. Longines has produced some incredible calibers throughout their history (foremost the 13zn and 30ch chronograph calibers), but their modern offerings aren’t really up to the quality of these vintage pieces. Nice watches at good prices, but not the in-house manufacture of the glory days.

 

As noted above, some Longines references are extremely desirable, but the OP watch is not, both because it's extremely small for a modern man's watch and also because the dial is repainted. I would say that the value is nominal.
