Case

Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.

Dial

Black. Like all Rolex Professional watches, the GMT-Master II offers exceptional legibility in all circumstances, and especially in the dark, thanks to its Superluminova display. The broad hands and hour markers in simple shapes – triangles, circles, rectangles – are filled with a luminescent material emitting a long-lasting green glow. Later versions of this watch feature the patented Chromalight display which glows blue.
