This gorgeous Rolex Red Submariner, ref. 1680 features a Mark V dial, the 5th version of the Red Sub dial. A clear indicator of a Mark V is the slightly open 6s in 660 Ft. This Red Sub has a 3.40 million serial number and the caseback is stamped IV.72. The dial is free of flaws, the markers, hands and pearl are all original and matching beautifully. The case is thick and likely never polished with wide, pronounced chamfers. This watch comes with the original Rolex Warranty with punched serial numbers. The bracelet is an updated, later bracelet.
