The Rolex Submariner Reference 16613 is a quintessential two-tone (Yellow Rolesor) luxury dive watch produced between 1988 and 2009. It is highly regarded by collectors as the last "classic" two-tone Submariner to feature an aluminum bezel insert and more tapered case proportions before the transition to ceramic bezels and "Super Cases".
