Rolex 278344rbr-0007 Datejust 31mm Stainless Steel – White Gold Diamond Oyster Dark Grey Diamond-set Dial Watch

Rolex Datejust 31 — Reference 278344RBR-0007

Presenting the refined and luminous Rolex Datejust 31 ref. 278344RBR-0007, a timepiece that melds Rolex’s technical precision with gem-setting expertise. With its 31 mm case, diamond-set bezel, and striking dark grey dial, this reference offers a blend of elegance, luminosity, and everyday wearability.

Case & Materials

The case is constructed in White Rolesor — Rolex’s signature fusion of Oystersteel and 18 ct white gold — offering both strength and radiant appeal. Its Oyster case design includes a monobloc middle case, screw-down case back, and Twinlock winding crown, ensuring water resistance to 100 m (330 ft). Topping the case is a domed, diamond-set bezel — a halo of brilliance fashioned with exacting craftsmanship. The gentle curve of the bezel gives the watch a soft luminous crown that accentuates the dial. Protecting the dial is a scratch-resistant sapphire crystal, with Rolex’s signature Cyclops lens magnifying the date window at 3 o’clock.

Dial & Gem Accents

The dial is finished in dark grey with a sunray pattern, delivering depth and dynamic light play as the wrist moves. Hour markers are diamond-set in 18 kt gold settings, combining sparkle with legibility. Polished white gold hands contrast against the dark grey surface, and the Cyclops lens ensures the date is immediately readable. The synergy of the diamond markers and the bezel halo creates a refined sparkle that never overpowers the dial’s clarity.

Movement & Performance

Under the hood 278344rbr-0007 powers Rolex Calibre 2236, a self-winding mechanical movement entirely devised and manufactured by Rolex. This calibre provides approximately 55 hours of power reserve. It features Rolex’s Syloxi silicon hairspring, Paraflex shock absorbers, and offers functions such as instantaneous date change and stop-seconds for precise time setting. After casing, the movement is certified as a Superlative Chronometer, operating within –2/+2 seconds per day.

Bracelet & Comfort

The 278344rbr-0007 is paired with Rolex’s robust Oyster bracelet, formed of three-piece solid links in Oystersteel. It is secured via a folding Oysterclasp, and features the Easylink 5 mm comfort extension link, allowing small adjustments in length for optimal comfort over the day. This combination ensures that the 31 mm case feels balanced on the wrist — offering presence without heaviness.
