The Datejust is one of the many classics that Rolex has put on the market. Since the introduction in 1945, the model has always evolved, but the original look has always been retained. Even the early versions still look very modern, which once again proves the classic status. The reference of this Datejust is 1603 and that means a steel bezel. The watch is from circa 1970. We were able to trace this based on the case number.
