Designed for women who value subtle sophistication and precision, this Datejust 31 is a masterpiece of aesthetic refinement and horological mastery.
Design & Aesthetic Excellence
The first thing that captivates the eye is its white mother-of-pearl dial, a design that blends depth with artistic grace. The dial is further enhanced with brilliant diamond hour markers that add a subtle sparkle, perfectly balancing elegance with Rolex’s timeless sophistication.
Encircling this stunning dial is a bezel set with round brilliant-cut diamonds, meticulously chosen and placed by Rolex gemologists to ensure flawless brilliance. The combination of the white mother-of-pearl dial and diamond-set bezel creates a refreshing, luxurious contrast that is both playful and opulent — a statement of refined taste.
Exceptional Craftsmanship & Materials
The Oyster case, crafted from corrosion-resistant Oystersteel, measures 31mm in diameter — the ideal size for slender wrists while maintaining a commanding wrist presence. The screw-down case back and Twinlock double waterproofness system guarantee a water resistance of up to 100 meters (330 feet), making this elegant timepiece as functional as it is beautiful.
The Oyster bracelet combines robustness with graceful proportions. Its flat three-piece links are designed for comfort and durability, while the Oysterclasp with Easylink extension system allows the wearer to adjust the bracelet length by approximately 5 mm for an optimal fit. The brushed and polished finishes highlight Rolex’s masterful attention to detail and craftsmanship.
Movement & Performance
At the heart of the Rolex Datejust 31 Ref. 278344RBR-0005 beats the Calibre 2236 — a self-winding mechanical movement entirely developed and manufactured by Rolex. Equipped with a Syloxi silicon hairspring, the movement provides exceptional resistance to temperature variations, shocks, and magnetic fields, ensuring optimal precision and reliability. With a power reserve of approximately 55 hours, the Calibre 2236 stands as a hallmark of Rolex’s technical innovation.
