Rolex Sea-Dweller 1665 "Great White" - Black Matte Pallettoni Dial - White Writing - Rolex Punched Warranty

The Rolex Sea-Dweller 1665, introduced in the late 1960s, is a legendary dive watch that played a pivotal role in Rolex's history of deep-sea exploration. Designed in collaboration with COMEX (Compagnie Maritime d'Expertises), it was developed to meet the demands of professional saturation divers who required a timepiece capable of withstanding extreme underwater pressures. As the first Rolex to feature a helium escape valve (HEV), the 1665 set the foundation for all future Sea-Dweller models, allowing trapped helium to escape during decompression without compromising the watch's integrity. The 40mm stainless steel case, significantly thicker than that of the Submariner, provided an impressive 610-meter (2,000-foot) water resistance, later increased to 1,220 meters (4,000 feet) in subsequent iterations. Unlike the Submariner, the Sea-Dweller lacked a Cyclops lens over the date window, a distinguishing feature that enhanced legibility under extreme conditions. One of the most collectible versions of the 1665 is the "Double Red Sea-Dweller" (DRSD), produced between 1967 and 1977, featuring two lines of red text on the dial reading "SEA-DWELLER / SUBMARINER 2000." These early dials went through several variations, making them highly sought after by collectors. Later versions, known as "Great White", dropped the red text in favor of an all-white print, marking Rolex's transition away from co-branding with the Submariner. Powering the 1665 was the Rolex Caliber 1575, a self-winding chronometer-certified movement with a date function and a hacking seconds feature for precise time setting. The watch was paired with an Oyster bracelet, ensuring both security and comfort for divers in extreme environments. As the first true professional-grade dive watch from Rolex, the Sea-Dweller 1665 remains one of the most historically significant and collectible Rolex timepieces. Its blend of innovation, rarity, and purpose-driven design continues to captivate both vintage watch enthusiasts and serious collectors worldwide. This stunning timepiece, dated from 1981, features its original punched warranty and has been kept in excellent condition.
