Pre-owned Rolex Submariner ref 116613LB (2019) is the modern evolution of the “Bluesy,” and it marked a big turning point when it debuted. This was the first two-tone blue Submariner to swap the old aluminum insert for Rolex’s Cerachrom ceramic bezel, a small change on paper, but a major upgrade in person. The ceramic bezel doesn’t fade, scratch, or wash out over time, which means that the deep sunburst blue dial and matching bezel keep their color year after year. It gave the Bluesy a sharper, glossier aesthetic compared to the warmer, slightly softer look of the older 16613. It still sports the classic formula: 40mm Oyster case, yellow Rolesor, solid-link Oyster bracelet, and the trusty caliber 3135 with a Quickset date. But the ceramic bezel, broader lugs, and updated bracelet gave this generation a more substantial wrist presence. Shop Rolex Submariner Collection
