This article delves into the world of vintage Rolex Submariners, specifically focusing on the iconic Rolex 1665 Sea-Dweller and the crucial role of its Triple Lock crown system. While the headline might seem misleading given the initial focus on NOS crown and tube sets, the connection lies in the essential components that define the water resistance and reliability of these highly sought-after timepieces. The availability of new old stock (NOS) parts underscores the enduring appeal and collectability of these vintage watches, and serves as a springboard to a broader discussion of the 1665 and its place in Rolex history.
FS: Rolex 24; FS: Very rare NOS Rolex 24: The initial listing of "new old stock" Rolex 24-702 crowns and tubes for various vintage Submariners (including the 5512, 5513, 1680, and Tudor Sub 7928, SD) immediately highlights a critical aspect of these watches: their maintainability. Finding NOS parts for vintage Rolexes is a significant advantage for collectors and enthusiasts, ensuring that these mechanical marvels can continue to function flawlessly for decades to come. The rarity of these NOS components elevates their value considerably, making them highly desirable among those dedicated to preserving the integrity of their vintage timepieces. The "FS" designation (For Sale) indicates a market where these essential parts are actively traded, often commanding premium prices reflecting their scarcity and importance.
1978 Rolex Sea; Vintage Rolex 1665 Double Red Sea-Dweller Mark IV Feature: The mention of a 1978 Rolex Sea-Dweller (likely a reference to a specific 1665 model) naturally leads us to a closer examination of the Rolex 1665 itself. The 1665, particularly the "Double Red" variant (with "Sea-Dweller" and "200m/660ft" printed in red on the dial), holds a revered position in the pantheon of Rolex dive watches. Its robust construction, incorporating the Triple Lock crown system, made it a reliable companion for professional divers. The Mark IV iteration, often associated with specific dial variations and hand styles, further adds to the complexity and desirability of this model within the collector community. Understanding the nuances of different Mark variations (based on dial, hands, and crown markings) is crucial for accurate identification and valuation.
Twinlock vs. Triplock: What’s the Difference? This crucial comparison sheds light on the technological advancement represented by the 1665's Triple Lock crown. While earlier Rolex models employed a Twinlock crown system, offering a significant improvement in water resistance over simpler crown designs, the Triple Lock system represents a further refinement. The Triple Lock system incorporates three sealing mechanisms, providing superior protection against water ingress at greater depths. This is a key differentiator for the 1665 Sea-Dweller, which was designed for professional diving applications demanding exceptional reliability and water resistance at significant depths. The enhanced water resistance facilitated by the Triplock system directly contributes to the 1665's enduring legacy and its popularity among collectors who appreciate the watch's robust engineering.
