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

The Rolex Lady-Datejust 31 is one of the most enduring and recognizable luxury watch references in the world, a timepiece that has defined elegance on the wrist for decades. Reference 278341RBRRSO represents a pinnacle expression of this lineage, pairing the precision engineering Rolex is celebrated for with the aesthetic sophistication demanded by today's discerning collector. At 31mm, the case occupies that ideal middle ground between the classic 28mm Lady-Datejust and the full-sized 36mm Datejust, offering versatility that suits both formal occasions and elevated everyday wear.

The case construction of this reference is built from a combination of Oystersteel — Rolex's proprietary 904L stainless steel renowned for its superior corrosion resistance and brilliant polish — and 18k Everose gold, Rolex's exclusive rose gold alloy formulated to resist fading over time. This two-tone configuration, sometimes referred to by collectors as Rolesor, creates a warm and luxurious aesthetic without sacrificing the durability and wearability of steel. The Oyster case itself is hermetically sealed, contributing to a water resistance of 100 meters (330 feet).

The dial of reference 278341RBRRSO is finished in slate, a sophisticated cool-toned grey that serves as a striking counterpoint to the warmth of the Everose gold elements. The slate surface is complemented by index hour markers that catch the light with quiet authority, giving the dial a clean, legible presentation that aligns with Rolex's design philosophy of purposeful restraint. It is a dial color that photographs beautifully and reads as deeply contemporary while remaining timeless.

Framing the dial is an 18k Everose gold domed bezel pavé-set with diamonds, an element that elevates this reference into genuine jewelry-watch territory. The domed profile is a classic Rolex form that predates the flat bezels of many contemporary sports references, lending the Lady-Datejust 31 a softly rounded silhouette that flatters the wrist. The diamonds are set with the precise tolerances Rolex applies to every gem-set component, ensuring uniformity of brilliance and security. The watch sits on an Oyster bracelet, Rolex's three-link flagship bracelet, which provides both comfort and robustness and is finished in the same Oystersteel and Everose gold two-tone treatment that defines the case.
