A rare gray and black two-tone dial in 14-karat yellow gold and 35mm cylinder design with a rare gray and black two-tone dial, made in the early 1940s, with an international masterpiece Cal.83. A large 35mm cylinder case, a rarity for the International, is used. The dial is an elaborate multi-colored dial with a black circle on a gilt grey dial with an embossed Arabic and a minute track on the base, a very rare example of the simple one-toned design often seen in international watches. The multi-colored dial that changes from light gray to dark gray depending on the angle of the light and the massive cylinder case that has aged to reddish-brown create a wonderful harmony and vintage taste. It is equipped with the famous Cal.83,  one of the most famous international watches.
