Rolex Datejust 31 Ref. 278240-0006
The Rolex Datejust 31 Ref. 278240-0006 embodies the essence of refined minimalism and timeless design. Crafted entirely from Oystersteel, this elegant timepiece presents a harmonious blend of strength, comfort, and understated beauty. Its silver sunray-finish dial, complemented by baton hour markers and a domed polished bezel, exudes modern sophistication while remaining true to Rolex’s iconic aesthetic.
Timeless Silver Dial
The watch’s silver dial is a statement of pure elegance and balance. Finished with Rolex’s signature sunray brushing, it reflects light in a captivating radial pattern that shifts gracefully with each movement of the wrist. The applied baton hour markers, meticulously crafted from 18 ct white gold to prevent tarnishing, offer exceptional legibility and refinement. Each marker and hand is filled with Chromalight luminescent material, ensuring a long-lasting blue glow in low-light environments.
A discreet date window sits at 3 o’clock beneath the Cyclops lens—a hallmark of the Datejust collection—providing effortless readability and reinforcing Rolex’s focus on functional luxury.
Oystersteel Case with Domed Bezel
The 31 mm Oyster case of the Datejust 278240-0006 is engineered from Oystersteel, a proprietary alloy developed by Rolex for exceptional resistance to corrosion and a lasting mirror-like polish. Its domed bezel enhances the watch’s smooth profile, delivering a softer, more fluid silhouette compared to the fluted version. Polished to perfection, the bezel captures and reflects light, emphasizing the clean symmetry of the design.
Thanks to Rolex’s hermetically sealed construction, the case guarantees water resistance up to 100 meters (330 feet), ensuring durability in all conditions. The Twinlock winding crown with double waterproofness system adds another layer of security, preserving the integrity of the movement within.
Refined Jubilee Bracelet
The Jubilee bracelet—originally created in 1945 for the debut of the Datejust—remains an emblem of Rolex sophistication. Its five-piece links combine polished and brushed finishes, creating a fluid and flexible feel on the wrist. The bracelet is secured with an Oysterclasp and equipped with the Easylink comfort extension link, allowing a quick 5 mm adjustment for perfect fit and comfort.
Precision and Performance
At the heart of the Rolex Datejust 31 Ref. 278240-0006 beats the advanced Calibre 2236—a self-winding mechanical movement developed and manufactured entirely by Rolex. Featuring the Syloxi silicon hairspring, this movement offers exceptional resistance to magnetic fields, shocks, and temperature variations. With a power reserve of approximately 55 hours and a precision of −2/+2 seconds per day after casing, the Datejust 31 guarantees impeccable reliability for daily wear.
Subtle Luxury for Everyday Wear
Designed for women who value elegance without excess, the Rolex Datejust 31 Ref. 278240-0006 pairs seamlessly with any attire—formal or casual. Its silver dial radiates quiet confidence, while the Jubilee bracelet ensures lasting comfort. From boardrooms to evening dinners, this watch represents an enduring icon of precision and grace.
