Pre-owned Rolex Submariner Date Ref. 16613 “Bluesy” (2007 – 2008) is often called the “Rolex Bluesy” for its pairing of a two-tone finish with a blue dial and blue bezel. The ref. 16613 is especially important because it belongs to the final generation of Bluesy models to feature an aluminum bezel insert. Rolex would eventually replace it with the ref. 116613, introducing a ceramic Cerachrom bezel and a more modern case design. As a result, the 16613 is the end of a classic era in Submariner history. Many enthusiasts prefer the aluminum insert because it has a warmer, more traditional appearance and can develop character over time in a way ceramic simply cannot. It has many of the proportions and charm collectors love about older Submariners while incorporating modern conveniences like a sapphire crystal and reliable self-winding movement. The result is a watch that feels equally at home in a collection focused on vintage Rolex or contemporary sports watches. Shop Rolex Submariner Collection
