Features

Legendary Movement: Powered by Rolex’s in – house Caliber 3235 self – winding movement, officially certified as a Superlative Chronometer for unmatched precision. The Oyster case structure ensures an astonishing 3,900m (12,800ft) water resistance, engineered for extreme deep – sea exploration.
Case & Bezel: Made from 904L stainless steel (Oyster case), paired with a black Cerachrom ceramic bezel with a unidirectional rotating design. The bezel’s black color contrasts strongly with the dial, and the case incorporates Rolex’s patented Ring Lock System for structural stability under extreme pressure.
Dial Design: A stunning gradient blue sunburst dial, decorated with large Chromalight luminescent hour markers (rectangular indices for maximum visibility). The iconic green “DEEPSEA” inscription and the magnified date window at 3 o’clock (using the Cyclops lens) add functional elegance, paying tribute to its deep – diving heritage.
Dimensions: True to the Deepsea series, it has a 44mm diameter and a robust shape, providing a bold yet balanced fit on the wrist, even with its substantial build.
Crystal: Equipped with a scratch – resistant sapphire crystal featuring Rolex’s Cyclops magnification, ensuring clear readability of the dial and date — crucial for underwater operations.
Strap: Comes with the iconic Oyster stainless steel bracelet, with solid, interlocking links designed for ergonomic comfort and secure wear. The bracelet includes Rolex’s GlideLock extension system, allowing for micro – adjustments to fit over a wetsuit or on bare skin.
Dive – Centric Innovation: Incorporates a helium escape valve (at 9 o’clock) to release accumulated gas during saturation diving, a vital feature for professional deep – sea missions. The Ring Lock System strengthens the case to resist extreme pressure.
Iconic Aesthetic: The gradient blue dial creates a captivating visual depth, complementing the watch’s technical excellence with a touch of artistic charm.
