Rolex Lady-Datejust 31 31 mm 278341RBRROSO Steel/Rose Gold/Diamonds Rose

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking, representing more than seven decades of continuous refinement since Rolex introduced the original Datejust in 1945. The Lady-Datejust line brought the same date-at-three-o'clock elegance to a smaller, more refined case, and the 31 mm format occupies a versatile sweet spot that suits a wide range of wrists while retaining the full visual presence of the Datejust family. Reference 278341RBRROSO is a flagship expression of this heritage, combining precious materials and diamond craftsmanship in a configuration that remains perennially in demand on the secondary market.

The 31 mm Oyster case of the 278341RBRROSO is constructed in Rolex's signature Oystersteel—an alloy of the 904L family prized for its exceptional resistance to corrosion and its ability to take a high mirror polish—paired with 18k Everose gold, Rolex's proprietary rose-gold alloy formulated to resist fading over time. The domed bezel is crafted entirely in Everose gold and set with a continuous row of brilliant-cut diamonds, elevating the profile of the watch and catching light from every angle. This two-tone material combination, often searched as steel and rose gold Datejust, is among the most recognizable and collectible pairings in the Lady-Datejust catalogue.

The rose dial is a beautifully warm backdrop that harmonizes naturally with the Everose gold tones of the case and bezel. Diamond-set hour indices replace the standard applied markers, adding depth and sparkle to the dial without overwhelming its clean, symmetrical layout. The date aperture at three o'clock remains the defining functional signature of every Datejust, framed here within a dial composition that balances horological utility with genuine jewelry-grade artistry. This dial configuration is frequently searched by buyers looking for a rose dial Rolex with diamonds, and the 278341RBRROSO answers that search definitively.

Powering the watch is a Rolex automatic movement, the self-winding mechanical caliber that keeps the Lady-Datejust accurate and low-maintenance for everyday wear. The Oyster case provides a water resistance of 100 meters (330 feet), a specification that underlines the watch's robust, tool-watch DNA even in this dressy, diamond-set configuration. The Oyster bracelet—three-link, polished center links flanked by satin-finished outer links in the Jubilee aesthetic of the Datejust family—secures the watch with the same engineering integrity as the case itself, ensuring comfort and longevity over years of daily use.

For collectors and first-time luxury watch buyers alike, the Lady-Datejust 31 278341RBRROSO represents an outstanding combination of intrinsic value, brand desirability, and wearable beauty.
