This article will delve deep into the world of the Rolex Sea-Dweller 1665, specifically focusing on a model with a serial number in the 5,7XX,XXX range, dating it to approximately 1979, offering a comprehensive review and exploring its place within the broader context of Rolex dive watch history.
Rolex Sea-Dweller Reference 1665: A Mark of Innovation
The Rolex Sea-Dweller reference 1665 represents a significant milestone in the evolution of professional dive watches. Introduced in the late 1960s, it was designed to meet the specific demands of saturation diving, a technique requiring divers to spend extended periods at significant depths. Unlike its predecessor, the Submariner, the 1665 boasted a helium escape valve (HEV), a crucial feature for preventing the watch crystal from imploding during decompression. This innovative addition was a game-changer, solidifying the Sea-Dweller's position as a true professional tool watch. The inclusion of the HEV, subtly positioned at 9 o'clock, immediately distinguishes the 1665 from its Submariner counterparts and other dive watches of the era.
Our focus piece, a 1979 model with a serial number in the 5,7XX,XXX range, embodies the quintessential characteristics of the 1665. Its automatic movement, a testament to Rolex's horological expertise, provides reliable timekeeping, even under extreme pressure. The robust case, designed to withstand the immense pressures of the deep ocean, exemplifies Rolex's commitment to durability and functionality. The iconic domed acrylic crystal, while susceptible to scratching, adds a distinct vintage charm that many collectors appreciate. Its slightly softer, more rounded profile compared to modern sapphire crystals gives the watch a unique aesthetic quality, reflecting the technology of its era.
Rolex 1665 Sea-Dweller Review: A Timeless Classic
A review of the Rolex Sea-Dweller 1665 inevitably centers on its exceptional build quality and performance. The watch is a rugged instrument, built to withstand the harshest conditions. The case, typically constructed from stainless steel, exhibits remarkable resistance to corrosion and impact.
