Rolex Datejust ref. 1625

THE REF. 1625 WAS PRODUCED FROM 1959 TO 1977.

Like the original Ref. 6202, the Ref. 1625 came in a wide variety of case metals and dial configurations. Listing them all here would be impossible. Ref. 1625 had the longest tenure of any Turn-o-graph and in 1977 it was replaced with the new references: 16253, 16263, 16264 and 16268. These variants all used the 27 jewel Caliber 3035 and did not have “Turn-o-graph” written on the dial. Instead, they read Superlative Chronometer Officially Certified at 6 o’clock. Why exactly Rolex chose to continue using the Turn-o-graph bezel without the name is unknown.
