Quite a rare bird! This timepiece built by Longines in ca.1950 should usually have the well known caliber 12.68, however, it has the older cal.13.3 which is in fact not interchangeable with 12.68 series. Since all the components of the watch are purely factory made and fit each other perfectly, we assume that this piece is one of those built by Longines using old factory stock of calibers from the 1920s. 

This particular piece is notable for sharp 35 mm case, charming silver dial, beautiful blue steel hands, and lovely historical caliber.

The watch went through complete service in June 2017. All stainless steel. Technical warranty: 1 year.
