Rolex 278384rbr-0010 Datejust 31mm Stainless Steel – White Gold Diamond Jubilee Dark Grey Diamond-set Dial Watch

Rolex Datejust 31 — Reference 278384RBR-0010

Introducing the elegant and refined Rolex Datejust 31 ref. 278384RBR-0010, a timepiece that masterfully merges gem-set luxury with Rolex’s signature engineering. With a 31 mm White Rolesor case, diamond-set bezel, and a dark grey sunray, diamond-accented dial, this reference offers luminous grace and precise performance.

Case & Construction

The case of this model is built in White Rolesor, Rolex’s proprietary combination of Oystersteel and 18 ct white gold — steel for robustness, white gold for luminous accent. Its Oyster architecture includes a monobloc middle case, screw-down case back, and a Twinlock crown, giving water resistance up to 100 meters (330 ft). Atop the case sits a diamond-set bezel, meticulously gem-set by Rolex’s master gem-setters — an artful halo that frames the dial and enhances its presence. A scratch-resistant sapphire crystal with the Cyclops magnifier over the date window ensures clarity and protection.

Dial & Distinctive Details

The dial is finished in a dark grey sunray texture, achieved through precision brushing that radiates from the center outward — creating subtle light play and depth. Its hour markers are diamond indexes set in 18 kt gold frames, which echo the bezel’s gemstones and lend a refined sparkle without overwhelming the dial. The date is displayed at 3 o’clock and magnified by the Cyclops lens for ease of reading. The harmonious contrast between the dark grey backdrop and bright gem accents gives this reference a balanced yet luminous aesthetic.

Movement & Performance

Under the dial, the Rolex Calibre 2236 drives the watch — a self-winding mechanical movement developed fully in-house. It provides a power reserve of approximately 55 hours and satisfies Rolex’s Superlative Chronometer standard (–2/+2 sec/day after casing). This movement incorporates modern horological enhancements — including instantaneous date change, stop-seconds for precise time setting, and robust internal architecture to maintain accuracy and reliability.

Bracelet & Comfort

278384rbr-0010 is paired with Rolex’s classic Jubilee bracelet in Oystersteel, composed of five-piece links that offer supple comfort and elegant articulation. The bracelet closes via a concealed folding Crownclasp, preserving a seamless visual flow on the wrist. The 31 mm case size, combined with the Jubilee design, results in a wearable proportion that feels both present and graceful.
