Shortly after Tudor discontinued their now-collected line of exotic manually wound chronographs, the new self-winding models were introduced around 1976. The earliest examples, such as this one, only featured the words Chrono Time on the dial. They were rapidly discontinued and the words OysterDate and Automatic Chrono Time around the sub-dial at six replaced them.
