Rolex 278344rbr-0031 Datejust 31mm Stainless Steel – White Gold Oyster Silver Diamond-set Dial Watch

Rolex Datejust 31 – Ref. 278344RBR-0031

The Rolex Datejust 31 Ref. 278344RBR-0031 is a consummate expression of refined elegance and Swiss craft. Designed for the wearer who values jewellery-level finish without sacrificing everyday performance, this 31 mm Datejust combines a luminous silver sunray dial with diamond hour markers, a domed diamond-set bezel, and Rolex’s robust Oyster bracelet. The result is a compact, wearable luxury watch that reads equally well at a gala or at the office.

Case & Bezel

The 31 mm Oyster case is forged from corrosion-resistant 904L Oystersteel and paired with white-gold appointments for a balanced White Rolesor aesthetic. The watch’s defining visual feature is its domed bezel set with brilliant-cut diamonds, expertly chosen and hand-set to form a continuous, luminous ring that enhances the dial’s radiance. The sapphire crystal is fitted with Rolex’s trademark Cyclops lens over the date window for crystal-clear legibility, and the case construction delivers 100 meters / 330 feet of water resistance via the Twinlock screw-down crown.

Dial & Hands

At the heart of Ref. 278344RBR-0031 lies a refined silver sunray dial that plays with light through fine radial brushing. Each hour position is offset by a diamond index set in 18k white gold, offering a tasteful balance of sparkle and legibility. Polished white-gold hands sweep across the face, providing clean contrast against the silver backdrop. The overall dial composition is restrained yet luxurious—diamonds emphasize the icons of time without overpowering the design.

Movement & Performance

Powering the watch is Rolex’s in-house Calibre 2236, a self-winding mechanical movement that incorporates modern advances such as the Syloxi silicon hairspring and Paraflex shock-absorbing components. Calibre 2236 is certified as a Superlative Chronometer after casing, guaranteeing precision to approximately −2/+2 seconds per day. With roughly 55 hours of power reserve, it combines daily convenience with mechanical excellence.

Bracelet & Wearability

Ref. 278344RBR-0031 is fitted with the classic Oyster bracelet in Oystersteel — a three-piece link design prized for its robustness and sleek profile. The bracelet secures with a folding Oysterclasp and features the Easylink 5 mm comfort extension, allowing quick micro-adjustments for optimal comfort in any condition. The Oyster bracelet enhances the watch’s versatile character: refined enough for formal wear yet solid enough for everyday life.
