In 1956, Vacheron Constantin launched an iconic watch: Model 6073 - one of the first self-winding water-resistant watches from Vacheron Constantin. The diameter of the watch is 35.5mm, made of 18K gold, with a bluish-green lettering. The dial naturally oxidizes to a salmon color. The case shape is excellent, the movement is new and bright, and the timekeeping condition is good. It is a rare treasure.
