The vintage Rolex Submariner 1680 Red Sub, specifically the MK5 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 nice vintage condition. The period correct MK5 dial shows all matching egg shell patina and is clean without any chips or scratches. The insert shows only very light wear. Case is sharp with some of its original champhers still present. This example comes head only on a strap and is running as it should.
