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.
