Rolex Datejust

Rolex Datejust : The Datejust models were introduced with a coin edge bezel, which later were replaced by a new fluted bezel along with a larger crown. In the mid-50's, Rolex introduced the Datejust (model 6605) with the cyclops, or the magnifying bubble that is placed over the date on the watch's crystal. In 1956, Rolex released a Datejust model called the "Thunderbird" (model 1625). This watch featured a Turn-O-Graph gold Bezel.
