30 years after the Submariner's debut, Rolex released the reference 16613 which boasted a two-tone steel and gold finish. Coveted for its luxurious yet functional design, two-tone Submariners were, and continue to be, a popular choice among avid Rolex collectors. The particular reference 16613 that is offered here today boasts an especially luxurious design with the addition of a champagne Serti dial topped with diamond and sapphire hour markers. French for setting, the Serti dial creates an elevated style that is appropriate for both black tie affairs and underwater adventures. The Submariner is always accompanied by a waterproof 40mm Oyster case, which is hermetically sealed for waterproofness up to 1,000 feet. This Rolex 16613 pairs the case with a matching two-tone Oyster bracelet and Oysterlock clasp.
