Rolex Datejust 31 — Reference 278344RBR-0018

The Rolex Datejust 31 Ref. 278344RBR-0018 is a striking expression of refined femininity, blending technical excellence with radiant beauty. This exceptional timepiece, part of the legendary Datejust collection, showcases Rolex’s signature craftsmanship through its harmonious combination of precious materials, flawless proportions, and enduring precision. The watch features a dark grey dial with baton hour markers, a domed bezel set with diamonds, and the elegant jubilee bracelet — all brought together in the captivating White Rolesor configuration (Oystersteel and 18 ct white gold).

Exquisite Design and Timeless Craftsmanship

The 31 mm Oyster case of the Datejust 278344RBR-0018 is crafted in White Rolesor — a signature blend of robust Oystersteel and lustrous 18 ct white gold. This pairing delivers both durability and luxurious brilliance. The domed bezel set with brilliant-cut diamonds elevates the watch with a dazzling halo of light, reflecting Rolex’s dedication to perfection in gem-setting. Every diamond is selected according to the brand’s uncompromising standards for clarity, color, and symmetry, ensuring unmatched radiance and refinement.

Captivating Dark Grey Dial

The dark grey dial offers a delicate contrast to the cool tones of white gold and steel, creating a sophisticated yet feminine aesthetic. The baton hour markers are crafted in 18 ct white gold to prevent tarnishing and are filled with Chromalight luminescent material for lasting readability in all lighting conditions. The date window at 3 o’clock is equipped with the iconic Cyclops lens, magnifying the numeral for optimal legibility — a hallmark of Rolex functionality. The dial’s subtle sunray finish enhances its depth, reflecting light in a graceful, ever-changing play of color.

Precision Movement: Calibre 2236

Inside the Rolex Datejust 31 Ref. 278344RBR-0018 beats the Calibre 2236 — a self-winding mechanical movement entirely developed and manufactured by Rolex. It features the innovative Syloxi silicon hairspring, offering exceptional resistance to shocks, temperature variations, and magnetic interference. Certified as a Superlative Chronometer, this movement guarantees an accuracy of −2/+2 seconds per day, surpassing traditional chronometer standards. With a power reserve of approximately 55 hours, it ensures dependable precision through workdays and weekends alike.

Bracelet Comfort

The Jubilee bracelet — a five-piece link design created in 1945 for the original Datejust — enhances the refined character of this timepiece. Crafted in Oystersteel, it offers exceptional comfort and fluidity on the wrist. The concealed Crownclasp closure ensures seamless aesthetics while maintaining a secure fit. The interplay of polished and satin-finished links gives the bracelet a captivating visual rhythm, complementing the brilliance of the diamond-set bezel.
