Rolex 278384rbr-0015 Datejust 31mm Stainless Steel – White Gold Diamond Oyster Silver Dial Watch

Rolex Datejust 31 — Reference 278384RBR-0015

The Rolex Datejust 31 ref. 278384RBR-0015 exemplifies Rolex’s mastery in balancing refined elegance with everyday robustness. This 31 mm ladies’ model combines White Rolesor (the union of Oystersteel and white gold), a diamond-set bezel, and a luminous silver sunray dial — forming a timepiece that radiates both prestige and versatility.

Case & Materials

The case employs Rolex’s White Rolesor construction, marrying the strength of steel with the luster of 18 ct white gold. The bezel is fully set with diamonds, combining a sleek domed curvature with gem-stone artistry that frames the dial in shimmering brilliance.  The watch leverages Rolex’s Oyster architecture — monobloc middle case, screw-down back, Twinlock crown — to deliver water resistance up to 100 meters / 330 feet.  A scratch-resistant sapphire crystal with the Cyclops lens magnifies the date display.

Dial & Visual Signature

Sporting a silver sunray dial, the ref. 278384rbr-0015 offers a refined and luminous backdrop for the hands and indices. The finish channels light in fine radial lines outward from the center, lending a dynamic play of light. The hour markers appear as clean stick indices in polished white gold, enhancing legibility and elegance. The date aperture at 3 o’clock is magnified by the Cyclops lens to ensure easy and quick reading. Contrasted against the diamond bezel, the dial maintains clarity, sophistication, and a balanced interplay of sparkle and minimalism.

Movement & Performance

At its heart beats Calibre 2236, Rolex’s in-house self-winding movement known for precision and reliability. The movement delivers a power reserve of approximately 55 hours, offering flexibility for daily wear or occasional rotation. Rolex certifies the fully assembled watch to its Superlative Chronometer standard (−2/+2 sec/day after casing). The mechanism incorporates instantaneous date change, a stop-seconds function for accurate setting, and internal enhancements for shock resistance and stability.

Bracelet & Wearability

278384rbr-0015 is fitted with the robust Oyster bracelet, crafted in Oystersteel with three-piece solid links. The clasp is a folding Oysterclasp equipped with Rolex’s Easylink 5 mm comfort extension, allowing micro-adjustments to ensure optimal fit and daylong comfort. The integration of the bracelet with the 31 mm case creates a graceful wrist profile — secure, elegant, and practical.
