Description
The Rolex Deepsea Ref. 136660 stands at the pinnacle of professional deep-sea diving watches, combining cutting-edge engineering with Rolex’s hallmark precision and durability. Crafted from corrosion-resistant Oystersteel and featuring a robust 44mm Oyster case, this watch is designed to withstand the extreme pressures of the ocean’s depths, while maintaining the elegance and reliability Rolex is known for.
This model features a striking intense blue to deep black gradient dial, famously known as the “D‑Blue” dial — a tribute to James Cameron’s historic solo dive to the Mariana Trench. The contrasting large Chromalight markers ensure excellent legibility even in total darkness, while the unidirectional rotatable bezel with a black Cerachrom insert allows for precise dive-time tracking.
The Calibre 3235 automatic movement inside is a powerhouse of Rolex innovation, offering enhanced efficiency, exceptional precision, and a 70-hour power reserve. Designed with the patented Ringlock System, Triplock crown, and a Helium Escape Valve, the Deepsea guarantees water resistance up to an extraordinary 3,900 meters / 12,800 feet.
Engineered for saturation diving yet refined enough for everyday wear, the Deepsea 136660 is a fusion of performance and presence.
