The vintage Rolex Sea-Dweller Ref. 1665 with a MK2 tropical brown dial is a remarkable example of one of Rolex’s most iconic professional dive watches. Originally designed for saturation divers in the late 1960s and 1970s, the 1665 "Double Red" is celebrated for its pioneering helium escape valve and robust 2000ft/610m depth rating. This particular example stands out with its MK2 dial that has aged into a rich tropical brown hue, offering stunning depth and warmth that only decades of natural patina can produce. The luminous markers and hands have developed a pleasing creamy tone, harmonizing beautifully with the dial’s transformation. The case remains in excellent condition, retaining sharp edges and strong proportions, while the matching bezel insert shows light wear consistent with age. A coveted reference among collectors, this MK2 tropical dial Sea-Dweller captures both Rolex history and the unique character that only time can create.

Today's example comes to us in excellent honest vintage condition. The polished case is excellent with thick crisp lugs. The bezel and insert are excellent showing a light denim fading. The tropical MK2 dial shows rich brown tones throughout and shows normal wear appropriate for its age. The caseback has the last 3 serial digits engraved on the inside. The 9135 folded link oyster bracelet is long with 12 total links + div extension. Here we have an excellent example with tons of charm and charecter with its rare mk2 tropical dial.
