Its dark grey sunray-finish dial with baton hour markers, adds a touch of contemporary freshness, while the diamond-set bezel enhances its luxurious presence. Designed for the woman who appreciates timeless design and technical precision, the Lady-Datejust 278384RBR-0020 is both a jewelry statement and a symbol of horological excellence.

Case Materials

The 31 mm Oyster case of the Lady-Datejust 278384RBR-0020 is a hallmark of Rolex’s legendary craftsmanship. Its construction in White Rolesor pairs robust Oystersteel with an 18 ct white gold bezel elegantly set with brilliant-cut diamonds. Each gem is meticulously positioned by Rolex’s in-house gem-setters to create a perfect circle of radiance. The case is hermetically sealed with a screw-down case back and Twinlock double waterproofness system on the crown, ensuring resistance up to 100 meters (330 feet).

Dial Hands

At the center of Ref. 278344RBR-0016 is a delicate dark grey sunray dial whose radial brushing plays with light to create subtle tonal shifts. Hour positions are marked by minimalist baton (stick) indices in white gold—clean, modern, and exceptionally legible. Polished white-gold hands glide across the dial, and the date aperture at 3 o’clock is magnified by Rolex’s signature Cyclops lens for instant readability. This restrained dial composition allows the diamond bezel to shine without overpowering the overall harmony.

Bracelet Comfort

Completing the timepiece is the sophisticated Jubilee bracelet, a five-piece link design that balances strength and suppleness. Crafted in Oystersteel, its alternating polished and satin finishes enhance its visual texture, while the concealed Crownclasp maintains a seamless aesthetic. The Jubilee bracelet, first introduced in 1945, continues to embody Rolex’s commitment to comfort and style — a perfect match for the Lady-Datejust’s timeless allure.
