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

278344rbr-0001 comes with the robust and elegant Oyster bracelet, crafted in Oystersteel with three-piece solid links. The Oyster design offers a balance of strength, comfort, and versatility. The clasp is a folding Oysterclasp, ensuring secure closure and a seamless look when fastened.
