Rolex Lady-Datejust 31 31 mm 278343RBROGRDVIJ Steel/Yellow Gold/Diamonds Green

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking, tracing its roots to 1957 when Rolex introduced the first Datejust sized specifically for women. Across decades, the Lady-Datejust has remained the definitive expression of elegance and precision on the wrist, combining Rolex's technical mastery with genuinely luxurious aesthetics. Reference 278343RBROGRDVIJ represents the modern 31mm generation of this storied line, a size that bridges the classic ladies' watch proportions with a contemporary wrist presence that reads beautifully on a range of wrist sizes.

The case of the 278343RBROGRDVIJ is constructed in a harmonious pairing of Oystersteel and 18k yellow gold, a combination Rolex refers to as Rolesor. Oystersteel is Rolex's proprietary steel alloy drawn from the 904L family, prized for its exceptional corrosion resistance and its ability to take and hold a mirror-bright polish. The interplay of the cool steel case flanks with the warm yellow gold crown and bezel gives this reference a distinctly dressy yet versatile character.

The bezel is one of the most striking elements of this reference: a yellow gold domed setting encrusted with diamonds that catch light from every angle. This diamond-set domed bezel elevates the 278343RBROGRDVIJ firmly into the haute joaillerie territory of the Lady-Datejust collection, making it equally at home at a black-tie event and an elegant afternoon occasion. Beneath it, the olive green dial with Roman numeral hour markers adds a rich, jewel-like depth of color that complements the gold and diamond surround with sophistication.

Powering the watch is a Rolex automatic movement, the hallmark of Rolex's commitment to precision and reliability. The watch carries a water resistance of 100 meters (330 feet) thanks to Rolex's Oyster case construction, which features a screw-down crown and caseback engineered to keep the movement protected. This means the Lady-Datejust 31 is not only beautiful but genuinely practical for everyday wear.

The five-link Jubilee bracelet is one of Rolex's most beloved and historically significant designs, originally introduced alongside the very first Datejust in 1945. On the 278343RBROGRDVIJ it is rendered in alternating Oystersteel and yellow gold links, adding a final note of refined luxury and ensuring the watch sits securely and comfortably on the wrist.
