The Rolex Oyster Perpetual Date just is a classic, iconic timepiece known for its timeless design and functionality. It was the first self-winding waterproof chronometer wristwatch to display the date in a window at the 3 o'clock position. The Date just is celebrated for its Oyster case, offering waterproofness and robustness, and its signature Cyclops lens, which magnifies the date for easy readability.
