New to the Longines forum but have a few that I will share over time. This recent acquisition from a dear friend:

 

Lovely piece, even the case and lugs look sharp! Pretty special to have friends like that...

 

Wow, what a lovely example. Can you share some details about this rare bird?

 

Oooooo, a 12.68Z Stop Seconds! I think you scored in a big way. Dial looks original to me too. I'll check my reference material tonight for more data to see what I have on that case style, but it looks like a 40's model.

 

Lucky man, that's a real beaut. Ive two 12.68z stops, but would kill for that one.
Congrats.
im guessing that's 37mm or so, from 1945/6.

 

Here they are, your's would look perfect along side them if you ever want to move it on.

 

Ref. 23074. Really love the round pusher.

 

Yes very fortunate 37.5mm I believe it dates from 1945 +-

 

Very nice! Perfect leather combination too! Enjoy!
