Rolex 278344rbr-0035 Datejust 31mm Stainless Steel – White Gold Diamond Oyster Blue Dial Watch

Rolex Datejust 31 — Reference 278344RBR-0035

Meet the radiant Rolex Datejust 31 ref. 278344RBR-0035, a jewel of horology combining Rolex’s refined aesthetics and mechanical excellence in a compact 31 mm format. This model blends Oystersteel and white gold with a diamond-set domed bezel, a dazzling blue sunray dial, and a sporty yet elegant Oyster bracelet.

Case & Materials

The 31 mm case is crafted in White Rolesor, Rolex’s signature fusion of Oystersteel and 18 ct white gold, giving the watch both strength and luminous presence. The bezel is domed and fully set with diamonds, forming an elegant halo around the dial and softening the case’s profile. The case follows Rolex’s Oyster architecture — monobloc middle case, screw-down back, and Twinlock crown — conferring water resistance to 100 meters / 330 feet. Sapphire crystal with Cyclops magnifier protects the dial and enhances the date window’s visibility.

Dial & Aesthetic Signature

Central to the 278344rbr-0035 is the bright blue sunray dial, with radial brushing that creates a subtle gradient and luminous depth as light shifts. Applied Roman numerals in polished white gold mark the hours, offering classic refinement against the vibrant backdrop. The date is displayed at 3 o’clock and magnified by the Cyclops lens for instant readability. The contrast between the blue dial, luminous numerals, and diamond bezel yields a timepiece that’s both eye-catching and legible.

Movement & Precision

Powering the 278344RBR-0035 is Rolex Calibre 2236, a self-winding mechanical movement that meets Rolex’s exacting standards. It provides approximately 55 hours of power reserve and is certified to the Superlative Chronometer standard (–2/+2 sec/day after casing). The movement incorporates advanced features such as instantaneous date change, stop-seconds for precision setting, and Rolex’s optimized internal architecture.

Bracelet & Wearability

This model comes with Rolex’s sturdy Oyster bracelet, composed of three-piece solid links in Oystersteel, offering both durability and refined wear comfort. It is secured with a folding Oysterclasp and includes the Easylink 5 mm comfort extension for on-the-go adjustment. The combination of the 31 mm case and the Oyster bracelet ensures the watch sits confidently yet comfortably on the wrist.
