The Rolex Deepsea reference 116660 in classic black is the benchmark professional saturation diving watch, designed for enthusiasts who demand the utmost in case engineering and commanding wrist presence. Boasting a muscular 44mm diameter and a 17.7mm thickness, the reference 116660 introduced the revolutionary Ringlock System—a three-piece case architecture featuring an internal nitrogen-alloyed steel support ring, a Grade 5 titanium caseback, and an extra-thick domed sapphire crystal. The monochrome black dial exudes purposeful elegance, accented by applied Chromalight indices that emit a clean blue luminescence.
Surrounding the dial is a unidirectional rotating bezel with a black Cerachrom ceramic insert, engraved with 60-minute graduations filled with platinum dust. The bezel turns with tactile 120-click precision, while the integrated helium escape valve at 9 o'clock provides the authentic functional aesthetic of commercial diving tool watches. The screw-down winding crown incorporates the Triplock triple-waterproofness system, featuring four micro-gaskets for airtight casing integrity.
Powering this deep-sea timepiece is a high-beat automatic self-winding movement beating at 28,800 vibrations per hour. The bidirectional oscillating weight winds silently during daily wear, offering steady amplitude and dependable accuracy. The date display at 3 o'clock snaps instantaneously at midnight, supported by quickset date manipulation and hacking seconds for precise synchronization.
Fitted with a solid Oystersteel Oyster bracelet, the watch wears securely thanks to the folding Oysterlock safety clasp and patented Glidelock slider, which allows effortless micro-adjustments in 2mm increments. Every timepiece is individually inspected, timegrapher verified for timing accuracy, and protected by our 2-year mechanical warranty.
