The Rolex Submariner Date 16613 is the long-running two-tone Yellow Rolesor Submariner that defined the model's modern era from 1988 through 2009 — a remarkable 21-year production run that made the 16613 one of the most produced Submariner references of all time. This 2001 example places production firmly in the modern Luminova era that succeeded tritium dial markers at the turn of the millennium, and after the introduction of solid end-link bracelet construction. The 40mm Oyster case combines Oystersteel and 18k yellow gold across both the case and the matching two-tone Jubilee or Oyster bracelet, depending on configuration, with a fluted gold-and-steel bezel housing the unidirectional rotating blue aluminum bezel insert. The blue sunburst dial features applied 18k yellow gold hour markers, Mercedes hands, and the cyclops-magnified date at 3 o'clock — the layout that has defined the Submariner for generations. Powered by the Rolex Caliber 3135 self-winding chronometer movement with a 48-hour power reserve, the 16613 carries COSC certification and beats at 28,800 vibrations per hour. Sapphire crystal, screw-down Triplock crown, and 300-meter water resistance preserve the watch's status as a credentialed dive watch. Full set includes Rolex box and papers. Pre-owned, 2001 production.
