Rolex Datejust 31mm Dark Grey 278240

Dark Grey Dial

Refined Technique and Subtle Light Play

The dark grey dial reflects refined watchmaking craftsmanship, enhanced by the signature sunray finish found in the Oyster Perpetual collection. This technique creates delicate light reflections that give the dial depth and a sophisticated visual texture.

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

As light moves across these engravings, it is evenly diffused, producing a subtle glow that shifts naturally with wrist movement. Once the sunray finish is complete, the dark grey 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 exceptionally strong and retains its integrity even in demanding conditions. Once polished, it achieves a refined, luminous finish that enhances its overall appearance.

Thanks to its resistance and durability, Oystersteel maintains its beauty over time, even in the harshest environments, ensuring long-lasting reliability and elegance.
