Rolex Deepsea Oystersteel

The Rolex Deepsea (Reference 136660) represents the absolute zenith of engineering for extreme underwater exploration. Designed to meet the most exacting demands of professional deep-sea divers, this ultimate ocean instrument features a robust architecture engineered to withstand crushing pressure at monumental depths.

The commanding 44mm case is masterfully sculpted from Oystersteel—Rolex's signature high-performance 904L alloy—and incorporates the pioneering Ringlock System alongside a nitrogen-alloyed steel memory ring. Its unidirectional rotatable bezel is fitted with a black Cerachrom ceramic insert graduated with a 60-minute scale to safely track immersion times. The intense black dial is highly legible, featuring oversized Maxi hands and hour markers coated in Chromalight that emit a long-lasting blue luminescent glow. Driven by the cutting-edge Manufacture Rolex Calibre 3235, this powerhouse movement delivers an exceptional 70-hour power reserve, making the Deepsea 136660 an incomparable statement of technical supremacy and luxury performance.
