The vintage Rolex Submariner 1680 Red Sub, specifically the MK6 variant, is a prized timepiece coveted by collectors for its historical significance and distinct features. The "Red Sub" nickname originates from the eye-catching red "Submariner" text on the black dial, distinguishing it from subsequent models. Produced from the late '60s to the late '70s, this watch boasts a stainless steel case, luminescent hour markers, a date window, and a unidirectional rotating bezel. Each "Mark" denotes specific production variations, with subtle differences in details like the font used for the date or alterations in the crown and bracelet design, influencing its rarity and collector appeal. Its place in Rolex history, coupled with its unique aesthetics, contributes to its high desirability and value among watch enthusiasts.

Today's example comes to us in original vintage condition. The period correct MK6 dial shows nice patina and some light tritium fading at the tip of the 12 o clock marker. The original tritium hands are slightly darker than the hr plots. Insert has faded to a nice blue hue. Pip is missing. Case has been polished. 9315 folded link oyster bracelet shows some stretch and light wear.
