A collector’s icon with everyday appeal, the Rolex Submariner 1680 is the first Submariner to feature a date—displayed under the signature Cyclops on its tall acrylic “top‑hat” crystal. This unpolished 40 mm stainless steel example retains sharp factory chamfers and crisp brushing, framing a matte black dial with warm tritium lume and a classic rotating bezel. Originally rated to 200 m/660 ft with a screw‑down crown and robust Oyster case, it delivers the purposeful tool‑watch feel that made the Submariner legendary. Produced from the late 1960s through the 1970s, the reference 1680 is powered by Rolex’s automatic Caliber 1575 with date—renowned for reliability and smooth timekeeping. Unpolished cases are increasingly scarce; this example’s honest patina and strong geometry make it an outstanding choice for the discerning collector seeking originality, character, and the quintessential vintage Sub look.
