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

The Rolex Lady-Datejust is one of the most storied references in watchmaking history, tracing its lineage to the original Datejust introduced in 1945—the first self-winding wristwatch to display the date in a window on the dial. The Lady-Datejust emerged to bring that same iconic design language to a more refined, smaller case calibrated for the wrist. The 31mm case size occupies a versatile middle ground, larger than Rolex's traditional 28mm lady's case yet still elegantly proportioned, and has become one of the most sought-after sizes in the modern Lady-Datejust lineup.

Reference 278341RBRARDVIJ exemplifies Rolex's mastery of mixed materials. The case pairs the cool, corrosion-resistant strength of Oystersteel—Rolex's proprietary 904L stainless steel alloy—with the warm, fade-resistant blush of 18k Everose Gold, a proprietary rose gold alloy exclusive to Rolex. This two-tone construction, sometimes referred to in the Rolex vernacular as Rolesor, gives the watch an effortlessly luxurious character that transitions seamlessly from professional settings to formal occasions.

The aubergine dial is the visual centerpiece of this reference and one of its most compelling selling points. A deep, saturated purple-brown hue reminiscent of ripe eggplant, aubergine is among the rarer and more coveted dial colors Rolex produces, giving the watch an artistic individuality that sets it apart from more conventional Datejust variants. Paired against the rose-gold warmth of the domed diamond-set bezel, the contrast is nothing short of breathtaking, with the scintillating diamonds drawing the eye and amplifying the richness of the dial color.

The domed bezel set with diamonds adds another layer of brilliance and three-dimensionality to the watch's profile. Rather than the flat, channel-set or pave bezels found on some models, the domed form echoes classic Rolex design heritage while the diamond paving ensures maximum light play. The five-piece Jubilee bracelet, a design introduced by Rolex in 1945 alongside the original Datejust, completes the package with its characteristic elegant links that drape the wrist with a fluid, jewelry-like feel. Together, the bracelet and case form an integrated, harmonious whole. An automatic movement powers the watch, delivering the reliable hands-free winding experience Rolex is renowned for, and the Oyster case provides water resistance to 100 meters, ensuring genuine everyday wearability.
