Footnotes
When Rolex introduced the Sea-Dweller Deepsea reference 136660 with the D-Blue dial, it honoured James Cameron's 2012 descent to the Mariana Trench, a journey to the deepest point on Earth. The dial's gradient, fading from a rich blue to a deep black, captures the transition from light to darkness beneath the waves - a quiet nod to the world of deep-sea exploration that has long inspired Rolex.
Engineered to withstand the extreme pressures of the deep, the Deepsea features a case reinforced by the patented Ringlock System, allowing water resistance to an extraordinary 12,800 feet. Its helium escape valve and uni-directional Cerachrom bezel reflect its professional diving pedigree, while the calibre 3235 automatic movement within offers a 70-hour power reserve, high efficiency, and exceptional reliability. Subtle refinements to the case, bracelet, and clasp give this latest reference a more balanced and comfortable feel without compromising its robust character.
A considered evolution within the Sea-Dweller lineage, this Deepsea embodies Rolex's enduring commitment to innovation and exploration.
