The Rolex Submariner Ref. 1680 "Red Sub" is one of the most iconic and sought-after vintage Submariners ever made. Produced from the late 1960s through the mid-1970s, this model was the first Submariner to feature a date, and the only one to ever feature the word “Submariner” printed in red — a detail that’s become legendary among collectors. The Red Sub combines classic tool-watch DNA with vintage Rolex charm: a matte dial, tritium lume plots, and a domed acrylic crystal that gives it that unmistakable old-school wrist presence. Early examples like this are becoming increasingly rare — especially when they retain original parts and have developed attractive patina over time. This is a must-have for serious collectors.
