rolex 666 | Rolex 16660 review

The Rolex Sea-Dweller, a name synonymous with deep-sea exploration and unparalleled robustness, has a rich and storied history. Among its various iterations, the reference 16660, often affectionately (and sometimes with a touch of superstitious intrigue) nicknamed the "Triple Six," holds a unique and significant place. Bridging the gap between vintage charm and modern functionality, the 16660 represents a crucial evolution in the Sea-Dweller lineage. This article will delve deep into the world of the Rolex 16660, exploring its design, features, historical context, and why it continues to be a sought-after timepiece among collectors and diving enthusiasts alike. We’ll also provide a comprehensive review and address frequently asked questions about this iconic watch.

The Sea-Dweller Legacy: Built for the Deep

Before diving into the specifics of the 16660, it's essential to understand the genesis of the Sea-Dweller. Rolex developed the Sea-Dweller in the late 1960s in response to the growing demands of professional saturation divers. These divers spent extended periods in pressurized environments, often working at depths far exceeding the capabilities of standard diving watches. One critical issue arose: helium ingress.

Helium, a lighter-than-air gas used in breathing mixtures for saturation diving, can permeate the gaskets of a watch during prolonged exposure to high pressure. As the diver ascends and the external pressure decreases, the trapped helium expands. If the watch case isn't equipped to handle this pressure differential, the crystal can pop off, rendering the watch useless.

Rolex's solution was ingenious: the helium escape valve (HEV). This one-way valve, typically located on the side of the case, allows helium to safely vent from the watch during decompression, preventing damage. The Sea-Dweller was born, a tool watch designed to withstand the extreme pressures and demands of the deep.

The Rolex 16660: A Pivotal Transition

The Rolex 16660 Sea-Dweller, produced from approximately 1978 to 1988, marks a significant transition point in the model's evolution. It replaced the earlier reference 1665 "Great White" Sea-Dweller, introducing several key upgrades that improved both its functionality and overall robustness. While the 1665 was a venerable watch in its own right, the 16660 brought the Sea-Dweller into a new era of performance.

Key Features and Specifications of the Rolex 16660:rolex 666

* Oyster Case: The 16660 retained the robust Oyster case, constructed from corrosion-resistant 904L stainless steel (although some early models may have used 316L). This case is designed to withstand immense pressure, ensuring water resistance to a depth of 2,000 feet (610 meters).

* Helium Escape Valve: As a Sea-Dweller, the 16660 features the essential helium escape valve, a crucial component for saturation divers. This valve ensures the watch can withstand the pressure changes encountered during decompression.

* Sapphire Crystal: A major upgrade from the acrylic crystal found on the 1665, the 16660 boasts a scratch-resistant sapphire crystal. This greatly enhances the watch's durability and legibility, particularly in harsh environments.

* Caliber 3035 Movement: The 16660 is powered by the Rolex Caliber 3035, a high-frequency automatic movement operating at 28,800 vibrations per hour. This movement offers improved accuracy and reliability compared to its predecessor. It also features a quickset date function, allowing for easy date adjustment.

* Uni-Directional Bezel: The 16660 features a uni-directional bezel, designed to prevent accidental movement that could shorten the perceived dive time. The bezel is marked with 60-minute graduations, allowing divers to track elapsed time accurately.

* Dial and Hands: The dial of the 16660 is typically black, with luminous hour markers and hands for optimal legibility in low-light conditions. The hands are often referred to as "Mercedes" hands, a design element commonly found on Rolex sports watches.

* Bracelet: The 16660 is typically fitted with an Oyster bracelet, known for its strength and comfort. The bracelet features a folding clasp with a diver extension, allowing the watch to be worn over a wetsuit.

Rolex 16660 Review: A Blend of Vintage Charm and Modern Performance

The Rolex 16660 Sea-Dweller offers a compelling blend of vintage aesthetics and modern performance, making it a highly desirable watch for collectors and enthusiasts. Its robust construction, improved movement, and scratch-resistant sapphire crystal make it a practical and reliable timepiece for everyday wear, while its historical significance and classic design give it a unique charm.

Pros:

* Improved Movement: The Caliber 3035 movement offers enhanced accuracy and reliability compared to earlier Sea-Dweller models. The quickset date function is also a welcome addition.
