Manufactured in the early 1930s, this is a rare and exceptional piece with an International watch featuring the Cal.87 movement and crafted from 935 silver material. It boasts a long rectangular silver luminous dial. Notably, it employs a hinge-style long rectangular case made of silver, a material seldom seen in vintage Internationals, apart from the usual '87' markings, making it a valuable early model from around 1931 with the Cal.87 movement. It also features luminous hands reminiscent of Cobra needles. This watch showcases the unique characteristics of older Internationals. Its excellent condition is evident, with the silver dial having evenly turned to a beige color, retaining the original luminous properties from that era. The precious silver case also preserves its original shape and hallmark.
