Rolex Datejust 31mm Blue 278240

Bright Blue Dial

Refined Technique and Luminous Finish

The bright blue dial reflects refined watchmaking craftsmanship, enhanced by the signature sunray finish found in the Oyster Perpetual collection. This technique produces elegant light reflections that bring depth, vibrancy, and a distinctive luminous character to the dial.

It is created using precise brushing methods that form fine grooves radiating outward from the centre of the dial, resulting in a perfectly structured and radiant surface.

As light moves across these engravings, it is evenly diffused, creating a subtle glow that shifts naturally with wrist movement. Once the sunray texture is complete, the bright blue colour is applied using advanced Physical Vapour Deposition (PVD) or electroplating techniques.

A final protective layer of varnish enhances richness, clarity, and durability, completing the dial with a smooth, polished finish.

Oystersteel

Highly Resistant to Corrosion

Rolex uses Oystersteel for its watch cases, a material specially developed to meet the brand’s highest standards of durability and performance. It belongs to the 904L steel family, widely used in high-technology industries such as aerospace and chemical engineering, where maximum resistance to corrosion is essential.

Oystersteel is highly robust and maintains its strength even in demanding environments. Once polished, it delivers an exceptional, refined finish that enhances its visual appeal.

Thanks to its resistance and durability, Oystersteel preserves its beauty over time, even in the harshest conditions, ensuring both reliability and lasting elegance.

The Jubilee Bracelet

Supple Comfort and Timeless Design

The Jubilee bracelet combines refined aesthetics with advanced engineering, offering exceptional comfort, durability, and precision. Its design, development, and production involve high-technology processes, while every bracelet and clasp undergoes stringent testing to ensure reliability and performance.

Alongside technical excellence, each component is carefully inspected by eye to guarantee flawless aesthetics and impeccable finishing.

Introduced in 1945 for the launch of the Oyster Perpetual Datejust, the Jubilee bracelet features a distinctive five-piece link design. Its supple construction ensures a smooth and comfortable fit on the wrist, making it a symbol of elegance and enduring craftsmanship.
