The Rolex Sea-Dweller reference 1665, affectionately known as the "Double Red" due to the prominent red text on its dial, holds a legendary status among watch collectors. Specifically, the Mark IV iteration, produced in 1978, represents a pinnacle of horological engineering and a highly sought-after piece of vintage Rolex history. This article will explore the intricacies of the Rolex 1665 Double Red Mark IV, examining its history, design features, market value, and the reasons behind its enduring appeal. We will also delve into aspects that make authenticating a genuine piece crucial, given the prevalence of counterfeits.
Rolex 1665 Sea-Dweller Review: A Pioneer of Depth
The Rolex 1665 Sea-Dweller wasn't just another dive watch; it was a revolutionary leap forward in underwater exploration technology. Released in 1967, it was designed in collaboration with Comex, a French underwater engineering company, to meet the demands of professional saturation divers. The increased water resistance, achieved through a helium escape valve (the crucial addition that distinguishes it from the Submariner), allowed the watch to withstand the extreme pressures experienced during deep dives. This valve, cleverly integrated into the case, allowed helium gas, used in saturation diving, to escape during decompression, preventing the crystal from shattering.
The 1665 represented a significant upgrade in materials and construction compared to its predecessors. Its robust oyster case, constructed from highly corrosion-resistant 904L stainless steel, provided exceptional durability. The sapphire crystal, a significant improvement over acrylic crystals used in earlier models, offered superior scratch resistance. The movement, typically a calibre 1575 (though some early examples used the 1530), was a robust and reliable workhorse, capable of withstanding the harsh conditions of underwater work.
Rolex Sea-Dweller Double Red: The Iconography of "Double Red"
The "Double Red" moniker refers to the striking red text on the dial. Unlike later Sea-Dwellers, which featured "Sea-Dweller" and "200m/660ft" in different colors, the 1665 Double Red prominently displays both inscriptions in red. This seemingly small detail is what elevates the 1665 Double Red to iconic status. It's a testament to a specific period in Rolex's history, a fleeting moment captured in time. The Mark IV dial, specifically from 1978, is particularly sought after, representing the final iteration of this iconic design before the transition to the single-red "Sea-Dweller" inscription.
The rarity of the Double Red Mark IV significantly contributes to its desirability. Production of this particular configuration was relatively short-lived, making genuine examples highly prized among collectors. The transition to a single red inscription marked a significant shift in the Sea-Dweller's aesthetic, solidifying the Double Red's place as a collector's item.
