A 1960 International Masterpiece "Ingenieur" model, Ref.666AD in stainless steel, equipped with the in-house caliber Cal.8531 Tropical grey dial. This is the first series of In Junior watches with a unique look of a calendar display laid out in the center of the dial and a Bombay dial, which is unique to the caliber 8531. The silver dial, which has changed to gray color evenly over the whole surface, shows a wonderful vintage taste, and although there are some minor scratches, the anti-magnetic screw back water-resistant case that retains the massive feeling that is characteristic of Injunior is a gem in excellent preservation condition.
