Pre-owned Rolex Submariner Date ref. 16613 Serti Dial (2000). The two-tone Submariner ref. 16613, affectionately known as the “Bluesy,” has long been one of the most recognizable watches in the Rolex catalog. Introduced during the late 1980s, it paired the rugged capability of the Submariner with the warmth and luxury of yellow gold, creating a watch that felt equally at home on a dive boat or at a dinner table. This particular example takes things a step further with a champagne Serti dial, one of the most distinctive dial options Rolex offered during the era. The term “Serti” comes from the French word sertissage, meaning gem-setting, and is used by collectors to describe Rolex dials fitted with precious stones. Here, brilliant-cut diamonds are paired with deep blue sapphires, creating a striking combination that complements the blue bezel and yellow gold accents beautifully. Shop Rolex Submariner Collection
