Citizen Chronomaster Non DateCitizen Chronomaster is one of the most exclusive watches in the 1960s and 70s era in Japan. It is a timepiece with a sophisticated design and a medal of the back of the eagle on the case back. The early model does not have a chronometer on the dial because there was no official chronometer institution in Japan at that time. The case has slight marks for its age. Overall excellent condition. The dial, hands, and markers are excellent as well.
