Rolex 278384rbr-0031 Datejust 31mm Stainless Steel – White Gold Diamond Oyster Dark Grey Diamond-set Dial Watch

Rolex Datejust 31 Ref. 278384RBR-0031 — Dark Grey Dial with Diamond-Set VI

The Rolex Datejust 31 ref. 278384RBR-0031 is a refined study in contrast: a deep, sophisticated dark grey dial paired with Rolex’s luminous gem-setting and robust Rolesor construction. Rendered in Oystersteel with 18 ct white gold accents, this 31 mm Datejust blends discreet modernity with traditional luxury—perfect for the wearer who values subtle strength and jewellery-grade finishing.

Striking Dial & Unique Numeral Accent

At the heart of this reference is a rich dark grey sunray dial that shifts from graphite to slate as light moves across its finely brushed surface. Applied Roman numerals in 18 ct white gold lend classical formality to the composition, while a signature flourish—the Roman “VI” set with brilliant-cut diamonds—creates an elegant focal point that catches the eye without overpowering the dial’s quiet poise. The date aperture at 3 o’clock is magnified by Rolex’s Cyclops lens for instant legibility, preserving the Datejust’s practical DNA.

Rolesor Case & Diamond Halo 278384rbr-0031

The 31 mm Oyster case is executed in White Rolesor—the practiced union of corrosion-resistant Oystersteel and radiant 18 ct white gold. Above the dial, a bezel fully set with brilliant-cut diamonds provides a soft halo of sparkle that frames the face with jewellery-level refinement. Each gem is selected and hand-set to Rolex’s exacting standards for color, clarity and alignment, creating a uniform and luminous bezel that complements the dark grey dial’s depth.

Oyster Bracelet — Strength and Comfort

Fitted on a solid Oyster bracelet in Oystersteel, the watch balances its dressy bezel with a purposeful, wearable attitude. The three-piece link construction offers durability and a contemporary profile, while the folding Oysterclasp (with Easylink 5 mm extension) ensures secure, comfortable daily wear. The bracelet’s brushed outer links and polished center links echo the case’s finish, delivering harmony between form and function.

Precision Movement

Powering the ref. 278384rbr-0031 is the in-house Rolex Calibre 2236, a self-winding mechanical movement designed for stable accuracy and lasting reliability. With a power reserve of approximately 55 hours and Rolex’s Superlative Chronometer certification (−2/+2 seconds per day after casing), the Calibre 2236 combines modern materials—such as the Syloxi silicon hairspring—with classic Rolex engineering to deliver dependable performance in everyday life.
