Understanding the Reference Number: Before we delve into the specifics of the watch itself, it's crucial to clarify the reference number. The correct reference number for this model is 116660.

Rolex Deepsea Review: A Dive into Durability and Precision
The Rolex Deepsea Sea-Dweller 116660 is more than just a watch; it's a statement. Its imposing size (44mm case diameter) and substantial weight immediately communicate its rugged nature and purpose. The robust Oyster case, crafted from 904L stainless steel, is renowned for its exceptional corrosion resistance and scratch resistance. This material, chosen for its superior strength and durability, ensures the watch can withstand the rigors of deep-sea exploration.
The unidirectional rotating bezel, a crucial feature for any diving watch, is fitted with a Cerachrom insert made from virtually scratch-proof ceramic. This ensures the elapsed dive time remains accurate and legible even under extreme conditions. The crisp, legible numerals and markers, combined with the luminescent Chromalight display, guarantee excellent readability in low-light environments, a critical safety feature for divers.
The heart of the 116660 is the caliber 3135, a self-winding mechanical movement renowned for its accuracy, reliability, and power reserve of approximately 48 hours. This movement, entirely developed and manufactured by Rolex, exemplifies the brand's commitment to in-house manufacturing and unparalleled quality control. Its precision is rigorously tested to meet Rolex's stringent standards, ensuring consistent and dependable timekeeping.
A standout feature of the Deepsea Sea-Dweller 116660 is the Helium Escape Valve (HEV). This ingenious mechanism allows helium atoms to escape the watch case during decompression stops, preventing damage to the crystal or case during saturation dives. This feature is essential for professional divers working in saturation diving environments, where they spend extended periods at significant depths.
The Glidelock clasp system on the Oyster bracelet allows for precise adjustment of the bracelet length, even when wearing gloves. This ensures a comfortable and secure fit at all times, regardless of the environment. The bracelet itself is meticulously crafted from the same 904L stainless steel as the case, maintaining the watch's overall robustness and elegance.
