First introduced in 1945 as the world's first self-winding wristwatch to display the date automatically, the Datejust has remained the cornerstone of the Rolex collection for over 80 years. The family spans four sizes — the Lady-Datejust at 28mm powered by the Calibre 2236, and the 31mm, 36mm, and 41mm variants powered by the Calibre 2235 or 3235, offering power reserves of up to 70 hours — ensuring the perfect fit for every wrist. Across all sizes, the collection is available in Oystersteel, two-tone Rolesor, and solid 18ct yellow, white, or Everose gold, with the 28mm and 36mm also offered with the iconic three-link President bracelet in full gold. Bracelet options include the sporty Oyster and the elegant five-link Jubilee — originally designed for the very first Datejust in 1945 — while bezel choices range from smooth and fluted to fully diamond-set. Dial colours span black, white, blue, green, champagne, chocolate, slate, and mother-of-pearl across the full range, with the bold red ombré edition available exclusively in the 31mm, making the Datejust the most versatile and personalised watch in the entire Rolex collection.
