The Oyster Perpetual Submariner Date combines Rolex's iconic diving-watch design with the refined contrast of Yellow Rolesor. The 41mm Oyster case and Oyster bracelet combine Oystersteel with yellow gold, while the black Cerachrom bezel features gold-coated numerals and graduations. The black dial is designed for clear legibility, with large Chromalight hour markers and distinctive hands. A Cyclops lens magnifies the date display at 3 o'clock, while the watch offers water resistance to 300 metres. Powered by Rolex Calibre 3235, the self-winding mechanical movement provides hours, minutes and seconds with instantaneous date adjustment and approximately 70 hours of power reserve. The Oyster bracelet is fitted with an Oysterlock clasp and Rolex Glidelock extension system.
