Rolex Datejust 31 31 mm 278344RBRGSO Steel/White Gold/Diamonds Grey

The Rolex Datejust is one of the most iconic and enduring watch families in horological history, introduced in 1945 as the first self-winding wristwatch to display the date in a window on the dial. Over decades the Datejust has evolved in size, material, and complication, yet it has always retained the refined, instantly recognisable silhouette that makes it universally desirable. The 31mm case size occupies a sophisticated mid-size position, flattering a wide range of wrists and appealing to anyone who appreciates understated, wearable luxury.

Reference 278344RBRGSO represents the contemporary expression of the Datejust 31 in Rolex's signature Oystersteel combined with 18k white gold. The Oyster case is renowned for its robustness and clean lines, and the two-metal combination elevates this reference into the realm of fine jewellery watchmaking without sacrificing the sportiness associated with the Oyster family. The 31mm diameter offers a presence that is confident and distinct, sitting comfortably at the intersection of dress watch and everyday companion.

The dark grey index dial lends this reference a contemporary, slightly moody character that separates it from more traditional silver or white dial Datejusts. Grey dials have become highly sought after in modern collecting circles for their versatility — they read as polished and formal under evening light yet appear cool and modern in daylight. The applied index hour markers add structure and legibility, a hallmark of Rolex's commitment to both aesthetics and function.

The 18k white gold domed bezel set with brilliant-cut diamonds is the crowning element of the 278344RBRGSO. The diamond-set bezel encircles the dial with an arc of brilliance that catches light from every angle, reinforcing the luxurious, jewellery-forward character of this reference. Paired with the Oyster bracelet — one of Rolex's most robust and time-tested bracelet designs — the watch wears with secure comfort and classic proportions. The Oyster bracelet's three-piece links create a fluid drape on the wrist that feels as natural as it looks refined.

Powering the watch is a Rolex automatic movement, delivering the precision and self-winding convenience that Rolex movements are globally recognised for. The combination of automatic reliability with 100 metres of water resistance means this is a watch built to accompany its owner through daily life without compromise. Whether worn to a board meeting, a formal dinner, or a weekend in the city, the Datejust 31 ref. 278344RBRGSO transitions effortlessly across occasions.
