In this comprehensive guide\, we delve into the fascinating history\, key characteristics\, and enduring appeal of the Rolex Sea-Dweller 1665 "Double Red" Patent Pending. From the Depths: The Genesis of the Sea-Dweller The Rolex Sea-Dweller was born out of a desire to push the boundaries of underwater exploration. In the 1960s\, professional divers needed a watch that could withstand extreme depths and pressures. In response\, Rolex developed the Sea-Dweller\, building upon the foundation of the Submariner\, to offer exceptional depth resistance. The original Sea-Dweller\, introduced in 1967\, was designated reference 1665 and boasted a water resistance of 610 meters (2\,000 feet). This depth rating was unprecedented for a wristwatch\, and it quickly cemented the Sea-Dweller's reputation as a robust and reliable tool for deep-sea diving. The "Double Red" Patent Pending: A Brief History The Rolex Sea-Dweller 1665 "Double Red" Patent Pending is a specific variation of the reference 1665 that is highly valued by collectors. Its distinctive feature lies in the red text "Sea-Dweller" and "Patent Pending" markings on the dial. The story behind the "Double Red" is tied to the evolution of the Sea-Dweller's dial. Initially\, the 1665 featured a black dial with white text. However\, in the late 1960s\, Rolex transitioned to a red "Sea-Dweller" inscription\, but kept the white "Patent Pending" text.
