The title "Rolex Oyster Perpetual 116660 V646829 Datejust" is slightly misleading. The reference number 116660 specifically designates the Rolex Sea-Dweller, a professional diver's watch, not a Datejust. The Datejust line has its own distinct reference numbers. The inclusion of "V646829" further complicates matters; this is not a standard Rolex reference number and likely refers to a specific serial number or internal designation, possibly from a retailer or independent seller. Therefore, this article will address the Rolex Sea-Dweller 116660, clarifying the inaccuracies in the original title and exploring its features, variations, and market value, alongside a discussion of how to distinguish it from a Datejust.
Understanding the Rolex Sea-Dweller 11660:
The Rolex Sea-Dweller 116660 is a robust and highly sought-after diver's watch, known for its exceptional water resistance and impressive durability. Unlike the more classic Datejust, designed for everyday wear, the Sea-Dweller is engineered for extreme underwater exploration. Its 1220-meter (4000-foot) water resistance surpasses that of most other diver's watches, making it suitable for professional saturation diving. This exceptional depth rating is achieved through a combination of advanced design features, including a helium escape valve.
This valve, located at 9 o'clock on the watch case, allows helium gas to escape during decompression stops after saturation dives. Without this valve, the pressure differential between the inside and outside of the watch case could cause damage to the crystal or even shatter the watch during ascent. The helium escape valve is a crucial element that distinguishes the Sea-Dweller from the Datejust and many other diver's watches.
The 116660 is characterized by its relatively large 44mm Oyster case, made of high-grade 904L stainless steel. This steel alloy is known for its resistance to corrosion and scratching, ensuring the watch's longevity even under harsh conditions. The unidirectional rotating bezel, also made of ceramic, allows divers to accurately monitor their dive time, preventing accidental miscalculations that could lead to dangerous situations. The ceramic bezel insert is highly scratch-resistant and maintains its color over time, unlike earlier aluminum bezels.
The dial is typically black, clean, and highly legible, featuring luminous hour markers and hands for optimal visibility in low-light conditions. The date window is located at 3 o'clock, a standard feature for most Rolex models. The movement powering the Sea-Dweller 116660 is the caliber 3135, a self-winding mechanical movement known for its accuracy, reliability, and robust construction. Rolex's meticulous attention to detail and rigorous testing ensures that each movement meets the brand's high standards of precision and performance.
