The Double Red Sea Dweller is a classic, and there is good reason why almost every vintage Rolex collector winds up with an example in their stash eventually — these are eye-catching, enduring and professionally competent tool watches.

Of all the dial configurations seen on the reference 1665, Mark II in particular has captured the attention of vintage Rolex aficionados from around the world. There are several characteristics that make the “Mark II” so widely revered and coveted. Firstly, the most apparent characteristic of this dial is the crisp and well-defined print of the lines “Sea-Dweller, Submariner 2000” in bright red. The font is also smaller on the second line. As seen on the present example, the dial occasionally changed color from a matt black to a gorgeous tone of light brown or chocolate color, otherwise known as a "tropical" dial.

This Double Red Sea Dweller is in excellent condition for its age, and was obviously well cared for by its original owner. The dial has metamorphosed into an incredible color of dark brown, giving it the look that all vintage Rolex collectors are after. The watch is in great condition, with the original punched guarantee, box and hang tags still retained. Most intriguingly, the watch was originally sold at Orologeria Svizzera — a widely celebrated watch retailer owned by the Panerai family, of which the first shop was opened up by Giovanni Panerai in Florence, Italy in 1860. Throughout the years, Orologeria Svizzera has been offering some of the best Swiss watch brands, including timepieces from Rolex and other top-tier manufacturers.
