A true icon of underwater exploration, the 40 mm Submariner Date unites a corrosion‑resistant Oystersteel case with a unidirectional aluminum dive bezel, calibrated for precise 60‑minute timing. Its matte‑black dial is punctuated by Chromalight hour markers and Mercedes‑style hands—each coated in long‑lasting luminescent material—to ensure flawless legibility, whether you’re at 300 meters below sea level or on deck. At its heart beats Rolex’s Calibre 3235 self‑winding movement, complete with a Superlative Chronometer certification and a 70‑hour power reserve. The Cyclops lens over the date window magnifies every detail, while the robust Oyster bracelet with Oysterlock clasp and Glidelock extension lets you fine‑tune your fit—over a wetsuit or on dry land.
