1930s Longines Cal.12.68z Staybrite 32mm Calatrava rare Black sector dial

This is a mid-1930s Longines watch equipped with the famous Cal.12.68z movement. It features a 32mm Staybrite case with a Calatrava design, and it is an extremely rare black sector dial model. The flat bezel adds to the beauty of the Calatrava case, which, although non-waterproof, carries the solid craftsmanship that is characteristic of Longines. The striking black sector dial showcases the aesthetics of the era, making this a precious and rare piece. It is powered by the renowned Cal.12.68z movement, which comes in various versions such as small seconds, central seconds, and stop seconds, and is one of Longines' signature movements. The half-gloss black dial with white lettering and the unique serial number engraved on both the case and movement are among the features that distinguish this model from later ones, adding to its charm.
