The Rolex Sea-Dweller Deepsea, specifically the reference 116660 with its iconic D-blue dial, stands as a testament to Rolex's unwavering commitment to pushing the boundaries of horological engineering and diving technology. This isn't just a watch; it's a statement, a symbol of extreme capability and refined luxury, a piece of history etched in steel and sapphire. This article will delve deep into the world of the 116660, exploring its features, its legacy, its price, and how it compares to its successor.
A Dive into the Deep: Technical Prowess and Design
The Sea-Dweller Deepsea 116660 boasts an impressive water resistance rating of 3,900 meters (12,800 feet), a feat achieved through meticulous design and the use of high-grade materials. This extreme depth rating solidified its place as one of the most capable diving watches ever created, making it a favored choice among professional divers and serious collectors alike. The watch's robust 44mm Oyster case, crafted from virtually indestructible 904L stainless steel, provides unparalleled protection for the sophisticated movement within. The signature Ringlock System, a unique feature of the Deepsea, plays a crucial role in achieving this remarkable water resistance. This system uses a patented ring made from a specially hardened nitrogen-alloyed steel to reinforce the crystal and case, distributing pressure evenly and preventing deformation under immense pressure.
The iconic D-blue dial is perhaps the most striking feature of the 116660. This gradient dial, transitioning from deep blue at the center to a lighter shade near the bezel, is both aesthetically pleasing and highly functional. The color gradient improves readability in varying underwater conditions, enhancing the watch's practicality for professional divers. The large, luminescent hour markers and hands ensure exceptional legibility even in the darkest depths. The unidirectional rotating bezel, also made of ceramic, provides crucial timing functions for decompression stops, a vital safety measure for divers. This ceramic bezel is scratch-resistant and highly durable, maintaining its pristine appearance even under harsh conditions.
The heart of the 116660 beats with the caliber 3135, a self-winding mechanical movement entirely manufactured by Rolex. Known for its reliability and precision, the 3135 movement boasts a power reserve of approximately 48 hours, ensuring the watch continues to function even after extended periods without wear. The movement is certified by COSC (Contrôle Officiel Suisse des Chronomètres), guaranteeing its accuracy and precision within stringent standards. This combination of robust construction, high-performance movement, and sophisticated design makes the 116660 a true masterpiece of horological engineering.
