Rolex 278344rbr-0001 Datejust 31mm Stainless Steel – White Gold Diamond Oyster Black Dial Watch

Rolex Datejust 31 — Reference 278344RBR-0001

Introducing the sophisticated Rolex Datejust 31 ref. 278344RBR-0001, a timepiece that fuses bold clarity with refined luxury. With its Rolesor construction (steel plus white gold), black dial with Roman numerals, domed diamond-set bezel, and Oyster bracelet, this model is an embodiment of powerful elegance.

Case & Material Construction

The case is crafted in Rolesor, Rolex’s signature combination of Oystersteel and 18 ct white gold — blending durability and prestige. The 31 mm case maintains a poised presence that suits a broad range of wrists. Its design follows Rolex’s Oyster architecture: a monobloc middle case, screw-down case back, and Twinlock winding crown to ensure water resistance up to 100 meters (330 feet).

Bezel & Gem Setting

One of the defining features of this reference is its domed bezel set with brilliant diamonds. The dome shape gives a soft halo effect to the dial, allowing light to dance across the gemstones while beautifully framing the face. The gem setting is executed with Rolex’s renowned precision — ensuring consistency in stone height, alignment, and brilliance.

Dial & Legibility

The dial is rendered in jet black, offering striking contrast to the white gold elements. Applied Roman numerals in polished white gold provide a classical and formal touch, enhancing legibility and elegance. The hands — also in white gold — maintain visual harmony and clarity. The date is displayed at 3 o’clock, magnified by Rolex’s signature Cyclops lens to ensure easy reading at a glance. The crisp contrast between black background and bright markers gives a clean, authoritative visual identity.

Movement & Performance

Inside, the 278344rbr-0001 Rolex Calibre 2236 powers this model — a self-winding mechanical movement developed fully in-house. It delivers a power reserve of approximately 55 hours, giving flexibility for occasional breaks in wear. Rolex certifies the completed watch to its Superlative Chronometer standard, promising precision within –2/+2 seconds per day after casing. Functions include center hour, minute, and seconds hands, instantaneous date change, and stop-seconds mechanism for accurate time setting. The internal design incorporates modern enhancements, such as shock absorption and optimized movement stability.

Bracelet & Wearability

The clasp is a folding Oysterclasp, ensuring secure closure and a seamless look when fastened.
