The Rolex Deepsea 136660 is an extreme dive watch built for the depths, with a 44 mm Oystersteel case and 3,900 m (12,800 ft) water resistance. Its striking “D‑Blue” gradient dial features Chromalight luminescent markers for excellent visibility in low light.
Powered by the Calibre 3235 automatic movement, it offers around 70 hours of power reserve and exceptional precision. The unidirectional bezel with black Cerachrom ceramic insert and platinum-coated graduations allows safe dive-time tracking.
The robust Oyster bracelet, fitted with an Oysterlock clasp and Glidelock extension, ensures a secure, adjustable fit — even over a wetsuit. Rugged, precise, and iconic, the Deepsea 136660 embodies Rolex’s mastery of professional diving watches.
