Rolex Datejust 31 — Reference 278344RBR-0029

Discover the refined elegance and technical mastery of the Rolex Datejust 31 ref. 278344RBR-0029. Designed for those who seek a perfect balance of sophistication and performance, this timepiece offers a unique marriage of craftsmanship, precious materials, and subtle glamour.

Case Materials

The 278344RBR-0029 features the Rolex hallmark White Rolesor construction, combining robust Oystersteel with lustrous 18 ct white gold. The case diameter is 31 mm, thoughtfully sized for wrists that demand elegance without excess. Its architecture is rooted in Rolex’s Oyster design — monobloc middle case, screw-down case back, and a Twinlock screw-down crown ensure water resistance to 100 meters / 330 feet. Over the dial lies a scratch-resistant sapphire crystal, enhanced with the signature Cyclops lens to magnify the date display.

Dial Gem Setting

One of the most striking features of this reference is its dark grey sunray dial set with diamonds. Radiating lines from the center create a dynamic effect under light, while the diamond accents add a discreet sparkle. Notably, the Roman numeral “VI” (6 o’clock) is large and embellished with 11 diamonds, lending a focal luxury note on the dial. The remainder of the hour indices are classic Roman numerals in polished white gold, creating a refined contrast against the dark backdrop. A domed, diamond-set bezel crowns the case, casting a soft halo of brilliance that subtly elevates the watch’s silhouette.

Movement Performance

Powering the 278344rbr-0029 is Rolex’s in-house Calibre 2236, a self-winding mechanical movement developed completely by Rolex. This calibre achieves a power reserve of approximately 55 hours. It also incorporates advanced features like the Syloxi silicon hairspring—engineered for thermal stability and resistance to magnetic interference—and Paraflex shock absorbers for increased durability. To meet Rolex’s high standards, the movement is certified to run within –2/+2 seconds per day after casing, under the Superlative Chronometer standard. Functions include center hour, minute, and seconds hands, instantaneous date change, and a stop-seconds mechanism for precise setting.

Bracelet Comfort

The Oyster bracelet in solid three-piece links (all in Oystersteel) provides both robustness and elegance. The clasp is a folding Oysterclasp equipped with Rolex’s Easylink 5 mm comfort extension link, enabling the wearer to fine-adjust bracelet length for optimal comfort. This subtle flexibility makes the 31 mm size wearable throughout varied conditions.
