1930s Longines Cal.15.26 rare 37mm Big Calatrava with Art-deco silver dia in Staybrite

This is a rare late-1930s Longines featuring the Cal.15.26 movement, housed in a 37mm Staybrite “Big Calatrava” case with an Art Deco silver dial. The large Cal.15.26 movement, which was also used in Czech military models of the same era, contributes to the watch’s substantial presence. The beautifully flat-bezeled 37mm case offers the weight and visual impact unique to pieces designed around oversized movements. The silver dial, highlighted by blued steel hands, features a well-balanced layout with a peripheral rail-track minute scale and an inner circular motif. With its richly aged patina, this piece exudes exceptional vintage character and charm.
