This Longines square Art Deco wristwatch dates to 1956 and reflects the refined geometric vocabulary of mid‑century design. Its compact, rectangular profile and restrained details speak to a period when case shapes explored elegance through proportion and line. At the heart sits the Cal. 9LT, a manually wound Longines movement of the era that illustrates the house’s emphasis on reliable, fine finishing. For the contemporary collector, a piece like this offers a direct connection to 1950s watchmaking and the enduring appeal of considered, architectural design.
