The Rolex Double Red Sea-Dweller (Ref. 1665) was introduced in the late 1960s as a professional dive watch developed with COMEX and U.S. Navy divers. Its nickname comes from the two lines of red text on the dial reading “SEA-DWELLER” and “SUBMARINER 2000.” Rated to 2000 feet (610 meters), it featured a helium escape valve—a ground breaking innovation for saturation diving. Produced until the mid-1970s, the Double Red 1665 is highly collectible due to its rarity and transitional role in Rolex’s dive watch evolution. Early models had “Mk” dial variants, each with unique typographic characteristics prized by collectors today.
