Rolex Datejust 31mm Dark Mother of Pearl 10 Diamond Rolesor Jubilee 278273

Overview 

The Rolex Datejust 31 reference 278273 is a masterpiece of organic beauty and horological precision. As a "Yellow Rolesor" model, it features the iconic marriage of 904L Oystersteel and 18k yellow gold, a combination that has defined Rolex luxury for decades. While the Datejust has been a cornerstone of the brand since 1945, this specific 31mm configuration—updated with the latest generation of Rolex engineering—is designed for those who seek a timepiece that functions as both a high-precision instrument and a piece of rare, high-jewelry art.

The defining characteristic of this reference is its Dark Mother-of-Pearl dial. Sourced from the inner layer of pearl oysters, this material is inherently unique; the natural variations in its structure mean that no two dials are identical. The "dark" variant is particularly prized for its mysterious, iridescent depth, shifting through shades of peacock blue, smoky grey, and violet as it catches the light. To further elevate this ethereal canvas, the dial is set with 10 brilliant-cut diamonds in 18k gold settings, replacing standard markers with a permanent shimmer. Framing this display is the signature 18k yellow gold fluted bezel, the ultimate mark of the Datejust’s prestige.

The watch is presented on the legendary Jubilee bracelet, the five-piece link design that is synonymous with the Datejust’s elegant heritage. In this Rolesor execution, the polished yellow gold center links provide a warm, radiant contrast to the brushed steel outer links. The bracelet features the concealed folding Crownclasp, which allows the intricate pattern of the links to wrap seamlessly around the wrist without a visible break—a refined touch that emphasizes its jewelry-like drape and exceptional comfort.

Technically, the 278273 is powered by the in-house Calibre 2236. This movement features Rolex's patented Syloxi hairspring in silicon, which is resistant to magnetic fields and provide higher precision than a traditional hairspring in case of shocks. Certified as a Superlative Chronometer, it offers a reliable 55-hour power reserve and an accuracy of -2/+2 seconds per day. With 100 meters of water resistance and a scratch-resistant sapphire crystal, the Dark Mother-of-Pearl Datejust 31 is a robust yet exotic timepiece, perfect for daily wear or the special occasion.
