Rolex introduced the Submariner 1680 in 1967 and continued to manufacture the reference until 1980. However, the 'Red' Submariner with its characteristic red name on the dial was only produced for the first part of the ref. 1680?s production run, until approximately 1975. Although Rolex only produced the red version of the Submariner ref. 1680 for a handful of years, Collectors have identified at least seven dial variations of which this is a MkV, not only did Rolex manufacture the red Sub for a relatively short period but examples with original dials are also seldom seen since many were furnished with later-era all-white dials during routine servicing,
