Rolex Deepsea 44 mm 116660M1 Steel Black Rolex Deepsea 44 mm 116660M1 Steel Black

The Rolex Deepsea reference 116660 is one of the most technically accomplished dive watches ever produced by a mainstream manufacture, and it sits at the very pinnacle of the Rolex professional sports collection. Introduced as an evolution of the legendary Sea-Dweller lineage, the Deepsea was engineered to handle extreme depths far beyond the reach of virtually any human diver, thanks to Rolex's patented Ringlock System — a nitrogen-alloyed steel ring, a domed sapphire crystal of exceptional thickness, and a solid case back working in concert to resist crushing underwater pressure. The result is a watch rated to 1,000 meters or more of water resistance, a specification that underscores why the Deepsea has earned a devoted following among professional divers, collectors, and adventurers alike.

At 44mm in diameter, the Deepsea 116660 wears with unmistakable authority. The stainless steel Oyster case is finished with Rolex's characteristic blend of brushed and polished surfaces, and the screw-down crown locks securely to protect the movement from moisture ingress. The ceramic bezel — virtually impervious to scratching and immune to UV fading — features the classic 60-minute graduated diving scale, making it as functional as it is beautiful. On the wrist, the watch announces itself as a serious tool, yet its proportions and detailing elevate it well above purely utilitarian territory.

The black dial of the 116660 is a study in legibility and restraint. Luminous hour markers and hands are generously sized, ensuring instant readability in low-light and underwater conditions where clarity can matter most. The dial's lacquered finish gives it a deep, rich character that transitions seamlessly from a wetsuit to a dress shirt — a versatility that explains much of the Deepsea's crossover appeal among collectors who want one watch capable of doing everything. The applied Rolex coronet at 12 o'clock and the distinctive "DEEPSEA" text on the dial reinforce the watch's identity as something genuinely exceptional.

Powering the Deepsea 116660 is a Rolex automatic movement, regulated to the exacting standards Rolex applies across its entire professional lineup. Rolex movements are chronometer-certified by COSC and then subjected to further in-house testing, ensuring precision and reliability that watch enthusiasts and working divers depend on in demanding conditions. The Oyster bracelet, crafted in stainless steel and secured by Rolex's Oysterlock safety clasp with a Glidelock extension system, allows fine length adjustments without tools — an important feature for divers wearing the watch over a wetsuit.
